Want to read

Transmigration

Only because both characters are openly gay

Note to self: if reading, ML is openly gay but his parents forced him to date a girl

Strong omega MC

Looks promising including ending. MC and ML broke up, MC is devastated and gets a phone call from ML to meet up. ML ends switching places with his highschool self. Spoiler alert but ML also meets MC of the past and asks what went wrong.

Love and falling out of love/taking it for granted.
