I mean, it's not revenge in the full sense of the word. It's like ML doesn't want MC first (can MC be chasing ML or not) And then the ML loves the MC but the MC does not care or is not interested ... something like that ... If you know of any manga or something, I'm also interested
Strategy to Capture that Scum Gong It’s quick transmigration and all the different arcs end in tragedy but all of them is B loves A who doesn’t treasure/care for B only to fall in love and desperately try to hold onto B. All the ML’s aren’t the most upstanding either (they’re pretty forceful/scummy) but it’s within MC’s plans so ¯\_(ツ)_/¯
Is it Iike that scum gong x cheap shou troupe or just a story full of mistakes misunderstandings and drama from themselves and third parties but the characters are actually pure and caring? If its the first one then Strategy to Capture that Scum Gong is definitely one... It has something like a sequel or a parody from the same author called The Scum Shou's Survival Guide If its the second, then sorry, i cant help... On just not fond of drama's and misunderstandings
How to Deal with a Tsundere Gong https://www.novelupdates.com/series/how-to-deal-with-a-tsundere-gong/ Kinda fits with it. Don't be mistaken with the title, ml is far for being a tsundere, for me, he was a low-grade scum. Childish Flower https://www.novelupdates.com/series/childish-flower/ The Decade of Deep Love https://www.novelupdates.com/series/the-decade-of-deep-love/ This one has a manhua version too: http://www.mangago.me/read-manga/10_years_where_i_loved_you_the_most/
Social Outcast ML is part of a clique that bullies MC, then he meets MC on a dating app and things change. You’ve Got Mail: A Cautionary Tale kind of fits? MC is in love with ML's pengpeng lol. Uhh lots of yaoi-esque sex so be warned.
