The girls noticed them putting the pieces together which resulted all of them face red knowing what they did last night and a little jealous of them having their time with him.

Houki and cecilia are jealous as well to see the girls glow understanding about it but held back because what they have told them about sharing him which made them a bit conflict.

Ichika: A new transfer student at this time of year?. Said with a surprise look.

They nod and cecilia smile.

Cecilia: Well I bet they want to see my skills. Said with a smile.

Which (y/n) shook his head amusing of cecilia act.

Student: Well the only students with a personal IS are us, class 3 and class 4, we should be fine. Said with a smile.

Then they got their orders and he noticed that she ordered ramen.

Y/N: Still your favorite huh. Said with a smile.

He went to the door opened to see rin outside with a bag.

Y/N: Rin what are you doing here?. Said with a questionable look.

Rin: I heard that you are roommates with those two girls from ichika. Said with a annoyed look.

Which narrow his eyes with a annoyed look.

Y/N 'thought': Note to self, prepare a harsh training section to give ichika no mercy. Said in his mind with a annoyed look.

Then she comes in and noticed kallen and cc in bed.

CC: Hello rin what brings you here. Said with a smile.

Rin looks at them.

Rin: Trade roommates with me so that (y/n) be comfortable with someone he knows better. Said with a serious look.

This got both of them to look at each other and then to their lover.

Kallen: (Y/N) wait outside please. Said with a menacing smile.

He knows that smile all to well along with cc and did what she told him.

Rin got a bit nervous seeing them look at her like that.

Kallen: Wanted to be roommates with (y/n), I see there is more than childhood friends. Said with a menacing smile.

CC agreed with her knowing what rin wants.

Rin trembling in fear seeing their look.

Kallen: What do you see in him rin?. Said with a menacing smile.

CC: No telling about his pilot skills. Said with with menacing smile.

Rin gulp in fear.

Rin: I didn't know he is a pilot too just from the news of ichika but I heard about another male here but didn't expect (y/n). Said with a fear look.

But she took a deep breath and gain her courage.

Rin: Look I don't see him as a skill full pilot which at first I didn't know about him as one, but I can see him as the same boy I met years ago before I moved to japan though that is the last time seeing him knowing he's on his training journey. Said with a serious look.

But then she sad smile.

Rin: But now he's here I can see he's the same but more serious of himself and more focused on becoming stronger, that's what I like about him which to be his lover but now I lost my chance because of both of you. Said with a sad smile

Both of them can see that she has feelings for him which they smile.

CC: Well rin you still have your chance. Said with a smirk.

Which brought her attention but then she eep because cc appeared from grabing her chest.

CC: Ooh, still have time to grow I see but (y/n) is gonna like it when he gives you a lot of pleasure. Said with a smirk.

Which rin blush even more about what she meant.

Rin: Aren't...aaahh...you two dating him?. Said with a confused and surprised look.

Kallen stood in front of her and place both hands on the young girl shoulder.

Kallen: We are indeed dating him, but we approve of him to get more girls in the harem and trust me his heart is big enough for us including you and the other two. Said with a smile.

Rin blush even more but then confused at what she said.

Rin: Other two?. Said with a confused look.

CC: Houki and Cecilia you met them at the cafeteria, both of them have feelings for him and we already talked to them about sharing him. Said with a smile in a lust manner.

Kallen: Yes and they must accept the fact to share him which you need to accept as well rin, think it over and come back to talk to us. Said with a smile.

This got her to think this over and cc let's her go.

Kallen went to the door letting (y/n) know to come in and he did seeing rin a bit conflicted.

She looks at him with a pleading look.

Rin: (Y/N) ummmm, do you remember our promise before I moved to japan. Said with a nervous look and blushing.

He smile knowing that time alright.

That brought her attention.

Y/N: The first one that next time we meet I can try your cooking remember that. Said with a smile.

Her eyes widen at that time remembered well.

Y/N: As for the second promise well you need to think about it and talk to kallen and cc first ok. Said with a smile.

This made her smile at that knowing he's very fateful.

Rin: Alright I'll think about it but I will do my first promise to cook you my best dish to blow your taste buds away. Said with a smile.
