So I got this really intense memory of reading this fic that I loved so much, but I can't find it anywhere. I've practically gone through my entire subscribed/bookmarked on here & AO3. 
It was a high school fic with good christian boy Jongin. He was friends with jongdae who was homophobic as hell and Jongin was just sort of confused.

Then he meets bad boy Sehun who is later revealed to be aromantic and they end up exploring Jongin's uality. Sehun gets Jongin to admit that he has feelings for his youth leader, Kyungsoo. Later, it is revealed that Kyungsoo is gay, but has a boyfriend, specially a teacher of Jongin's school.

Also Sehun has loaded parents, but there are really cold and mean to him, so he is really sad.

I remember Minseok and Luhan being together, with them being in a ddlb relationship. 

There is also a part where Kyungsoo's boyfriend cheats on him with a student (Jongdae) and in a moment of weakness, Kyungsoo sleeps with Jongin and immediately retreats it, which really upsets Jongin. 

The ending has to do with them all hanging out and smokin pot and the cops showing up, Sehun sacrificing himself because Minseok got hurt, and Sehun being sent away to boarding school. 

The epilogue involved Sehun and Jongin living together while Jongin went to college and the later Kyungsoo and Jongin reconnecting and getting together.

If you could please help me find this fic, I'd be indebted to you forever, I've been searching for it for so long. 
Thank you so much.
