Adding emotion to chapters can be tricky to do, and this really depends on what kinda story you're writing.

Obviously there are many different kinds of angst you can throw into your story and everyone writes it differently, but I'm just gonna go with a couple basic ones.

An ex comes in, a misunderstanding, breakdown with someone there to help, or opening up on stuff they bottled up.

The best thing to do with angst is have it scattered out throughout the story so it's not so much a surprise.

When that climax scene does come about, there are many different ways to tackle it.

The misunderstanding one is something I use very often. It's that scene where the characters are running to each other in the rain and are crying, saying how they understand and how they really do love them.

These can go hand in hand with the ex character as I did in Bittersweet Coffee; however, in a more recent story, the misunderstanding was more wrong place wrong time type of thing.

Building up the emotion can be hard, but it all relies on that chapter where it spills out.

These chapters have shouting, crying, moments of silence and understanding, and even heartbreak at times. When the angst happens, say maybe Scott told Jimmy that he was really the Champion of Aeor and didn't wanna hide it anymore. Scott would probably show Jimmy, go on a huge long rant (feel free to add tears here) and at the end there's some fluff with Jimmy hugging Scott saying he still loved him.

It definitely works better if you have it sprinkled into the story and remind us of the person's past, maybe throw in some flashbacks or chapters in the ex's perspective, before leading up to that main chapter where things take a turn.

Helping the chapter flow though heavily relies on you.

How you see the characters, how you envision them acting, talking, what they're wearing, are they avoiding eye contact, are they talking clearly.

Just being able to picture it and getting to know the character helps. It comes with time, like just recently I finally was confident in my ability to write Jimmy and Joel's characters. A lot of people are very complicated (Grian- I swear I could write a whole chapter about how hard this man is to write-) but once you get comfortable and learn them and their style it gets easier to figure out speech patterns and how they'd act.

EX for angst:

"Look, Martyn, I...I didn't mean to come off so rudely." Ren glanced over at the blonde. "I don't want this tension to be between us."

"Then stop glaring at me! Stop- stop being such an a-hole to me!" Martyn shouted and Ren looked down.

"Okay, yeah maybe I have been childish with the way I'm handling you being in the show with me but- I- I'm doing my- "

"Your best? You'd probably kiss a toad than smile at me." Martyn shot back and Ren sighed.

"No, I- ...I genuinely am sorry for the way I've been treating you." Ren said in a quiet voice and Martyn hesitated.

"I don't want to hurt you more than we've already hurt each other."

"Shift the blame onto me as always." Martyn sighed heavily.

 Ren continued, frustrated but determined to get this over with.

"It's hard for me to look at you the same, but it'll get easier the more I talk to you." Ren sighed, realizing how confusing he just sounded. "I just...I guess I'm just not completely over our breakup. I'm not saying I still like you I'm just saying that...it was a lot, you know?"

Martyn mumbled something but nodded.

"I'm sorry your date didn't show, I really am." Ren stood up and dusted his pants off before glancing down at Martyn. "I'll see you during tech week, I guess."

Martyn looked up at him for the first time since Ren had said hi.

"I...thanks." Martyn whispered and Ren smiled weakly.
