Everything you wanted exist in this one:
https://www.mangago.me/read-manga/radio_storm/
https://www.mangago.me/read-manga/momentum_park_ji_yeon/ => this one has multiples stories, it fishined me honestly. This is poetic, angsty and beautifully written. Give it a try !
https://www.mangago.me/read-manga/reunion/ => PEAK story and rlly sad. It was a cinematic masterpiece. A classic angsty story
https://www.mangago.me/read-manga/ouroboros_1/ => one of my trauma tbh this author KNOW how to crush you (the other story "lovesick dog" is rlly good too !)
https://www.mangago.me/read-manga/perle/ => you will understand what crying means after this one T_T
https://www.mangago.me/read-manga/alien_stage/ => I will never shut up about Alien stage. If you don't know, this is a serie of videoclips on ytb with A LOT of backstory (on patreon, and you can find informations on the socials). Watch the videos first and then read this. The fandom is incredible and SO depressed. This is my entire personality now...
https://www.mangago.me/read-manga/a_married_man/ => my ORIGINEL trauma. Like. I felt physical pain reading this. Good luck...
