Hana goes into the Room 207 mailbox and smiles seeing a letter addressed to her. 

My dear little star,

How is my favorite person in the world doing? I've been doing well overseas. Medical school is going great and don't worry, I always have a butterscotch candy to cheer me up if I'm feeling down. And I haven't accidently slept on a bench or bus again. I'm glad to hear that your acting classes and performances are going great. When I have the opportunity to see another one of your performances, I better get a front row seat before your boyfriend does! I still want to meet him and make sure that he's good enough for you! I don't care what Hye Ryung says! Oh, and has Young U really still not written back to Young Ro? Next time we're all together, you and I will straighten him out. And the fried chicken is on me!

Sincerely, your first fan

P.S.

Protect that cute face of yours because I'm going after those cheeks! Hye Ryung informed me about your little wall climbing experience!

"Darn! Teddy snitched!" She mutters with a pout, not noticing Young Ro's arrival.

"Who did you get a letter from Hanny?" Young Ro asks, resting her chin on her shoulder.

"It's from Beany!" Hana giggles. "... Oh, and he mentioned you! I think he might confess his undying love for you soon!" She teases.

"Hanny, stop that!" Young Ro whines while blushing and runs away.

Hana giggles and chases after her.

"Hana, I appreciate this but isn't this too much?" Soo-ho asks his girlfriend who is giving him a back massage.

"Nope! I have to take care of you until you're fully recovered!" She giggles. "Now just relax!"

"...Did something good happen? You're giggling more than usual." He asks her with a smile.

"Well-"

"My little star! Where are you?! Your first fan has returned!" A voice shouts.

"...Huh?" She blinks repeatedly hearing that nickname. "Is that...?"

"Nam Hana!" The voice shouts again.

Soo-ho pouts from the loss of his girlfriend's hands on him as gets up and hurries over to one of the windows. He goes to follow her and wraps his arms around her.

"Do you know who's calling you?" He asks.

"Oh...my...god!" She squeals and quickly turns around to kiss her boyfriend's cheek. "Eat some butterscotch candy and cuddle with my bambi plushie! I'll be back later, okay?!"

She runs out of the attic to hurry outside, leaving a confused Soo-ho. Once outside, she tackles the one who was calling for her in a hug.

"Hee Tae!" She squeals, jumping up and down excitedly.

Lee Do-hyun as Hwang Hee Tae

"Oh, my precious little star!" He laughs, hugging her back just as tightly. She squeals even louder as he lifts her up and spins her around.

"I missed you, my Beany!"

"I missed you more! Here let me look at you." He puts her down and pulls away, cupping her face in his hands. "Hana... Did you get cuter? Yah, didn't I tell you not to grow up so fast? You're making me miss stuff."

"Sorry!" She giggles.

"It's al-" Suddenly a shoe is thrown at Hee Tae's head. "Ow!"

"Why didn't you call for me too?!" A voice yells, making the two look up to see Hye Ryung glaring at Hee Tae from the window of Room 207.

"I just saw you five minutes ago!" He yells back. "And what if your shoe ended up hitting our little star?!"

"I never miss my target!"

"Teddy, I'm giving you a pinch later for being mean!" Hana yells and sticks her tongue out.

"And did forget what I told you?! I said that I would sell the next shoe you threw at me!"

"Try it and see what happens! You know how strong my punches are!"

Young Ro comes up beside Hye Ryung and her eyes widened seeing her longtime crush.

"Nice to see you, Young Ro!" Hee Tae sends her a big smile and waves.

Young Ro blushes and waves back, ignoring Hana who is wiggling her eyebrows. Seol Hui and Jeongmin come up next to the girls and also wave at Hee Tae.

"Hello, girls!"

"Eun Young Ro!"

Hana and Hee Tae look behind them to see the voice belonging to the person is none other than... 

"Young U oppa!" Young Ro shouts, happy to finally see her older brother.

While waiting for her to come down to them, Hee Tae flicks Young U's forehead.

"Ow! What was that for?!"

"For not writing back to my twin, you butthead!" Hana sticks her tongue out at him.

"Yeah, you really can't take the time to write one letter your one and only sister? Yah. I'm busy too but that doesn't stop me from writing to my little star when I can. Is one letter too much to ask for?" Hee Tae is about to flick him again, but Young U shields his face.

"Alright, alright! I'll do better! Sheesh... And Hana? Is there ever going to be a day when you don't call a man a butthead?" Young U asks, ruffling her hair.

"That would be my boyfriend!" She tells him, smacking his hand away.

"And he's the first man you haven't called a butthead? He must be a good one then." Young U says.

"So when do I get to meet him?" Both the guys ask.

"Umm... He's out of town right now..." She lies, giving them both butterscotch candy.

"Really? Damn, he got lucky. Just wait till next time!" Hee Tae mutters.

"Don't run. You'll fall." Young U tells a running Young Ro as he opens his arms for her, giving her a hug. "How have you been?"

As the siblings are having their moment, Hee Tae turns to Hana and places his hands on her shoulders.

"...Hana."

"Hmm?"

"Did you get my letter?"

"Yep, I got it this morning..." Hana's happy expression slowly turns into a scared look. "Oh..."

"Yeah." He quickly cups her cheeks and starts squishing them. "What were you thinking climbing the wall to get back into your room?! You could have broken one of your precious little limbs!"

"Hee...Tae... Please!"

"As punishment, you're drinking only white milk for a whole week!"

"Any...thing...but...that...please!"

The siblings laugh at their interaction and the four of them are unaware of a jealous guy watching them from the fourth floor's window...

"Didn't Young Ro say that her brother couldn't take a leave? And who was that guy that you were hugging?" Soo-ho asks as Hana treats his wound.

"Well, I guessed he managed to find a way to take one. And that was Hee Tae! I told you about him, remember? You know how Hye Ryung is like my mom friend well he's my dad friend!"

"Ah, your friend who's in med school... I see." He lets out a breath of relief.

"They're some of the most precious people in the world to me, just like you." She says with a smile and notices him fiddling with his pigeon necklace. "Your sister was right about that dove keeping you safe. It led you to your bodyguards."

He laughs. "Su-hui would love you."

"Everyone loves me! How could they not?" She puts her hands over her cheeks and gives him an adorable expression. "Oh, did I smell jealousy in the air a moment ago?"

"Who... Who was jealous?" He mutters, looking away.

"Didn't I tell you that Roro has a crush on him? I'm going to set them up!" She giggles. "Ooh, we should go on a double date sometime!"

"How is a sweet girl like you so mischievous?" He laughs once more, holding her close to him and begins to gently stroke her back. "You climb walls. You threw a spoon at your sister-figure's ex. You almost punched a clown. You held your ground against cops. Now you're a matchmaker?"

"Hey...how did you pronounce your German name again?" She suddenly asks.

"...Beschutze deinen geliebten." He answers, smirking.

"...I still got nothing but belly out of that." She mutters, making him laugh. "Keep teasing me and your new nickname is going to be Belly!"

She gets out of his grip and stands up, accidentally knocking over a cup of juice into the first aid box.

"Oh no!" She whines and tries to clean it until he stops her.

"Let me take care of this, okay? You go clean this." He gently says to her, placing a cloth in her hand.

As she goes to wash the cloth, she doesn't notice the water that leaks from the sink and gets onto the floor, soon going through a floor drain that is above the library...

"I'll be seen easily by the cops, so not that way. How about basement level two?" Soo-ho asks as the couple look over a map of the dormitory.

"The mechanical room and Man Dong's room are there."

"Any way out from basement two?"

"I don't think there is. One time Roro and I were running late for roll call we couldn't find a door to the basement. The others said there aren't any." She answers him as he puts his hand on his forehead, frustrated with the situation.

"So the only way out is the main gate?"

"Yep... Unless you wanna climb down again." She says, getting a small laugh out of him. "To the right is the staircase. This staircase is the only way up and down this rooftop. And no one ever goes near this attic because of the spooky story."

He gives her a small smile and brings her close to him. "At least I have you."

"You're a lucky man!" She smiles back at him and his soon becomes a frown. "Hmm? Someth-"

He signals her to be quiet and they hear Man Dong coughing, letting them both know that someone else is with him. The couple's eyes widened as his grip on her waist tightens, bringing her closer to him.

Episode two is done! How was it?

Yep, I did it! Youth of May crossover! I can't believe that I did this, but I did! I was debating whether I should do it but I kinda wanted Young Ro to have a love interest as well and he was the first person who came to mind so... Also, since Hye Ryung is like one of those momlike friends, I wanted Hana to have dadlike friend. And I wanted to include one more scene, but I'll save it for next chapter! We got some more scenes with Hee Tae coming and I'm really excited for it!

How do you feel about Hana's relationship with Hee Tae?

I tried to include a scene with her mom, but I'll wait till next episode. Hopefully I can figure something out.
