Sevuritus recs

Guys ive been searching this sub for new recs but nothing is giving what i need it to give

My fav is O mine enemy (kirby lane i think)
I also liked
- to trust
- a year like none other
- two weeks
- crime and punishment
I read a few others that were decent but i cant remember the names. I like slow burn severitus and when the characters stay canon. Like snape cares but hes not all mushy and harry is reserved. I dont like biological dad trope or even when harry starts calling snape dad✋🏽
Plwase scratch my itch
