Ambi's activites

Hi:) someone pls help me find a bl manga. I don't remember much but mc is a highschooler and he meets ml in an abandoned house and hinks ml doesn't have any place to stay nor any money?

Isekai, the usual transmigration, reincarnation, time travel etc. except, you know, it's gay

I love reading egoist MLs suffer when the FL moves on from loving them, apologising & regretting. 

Ratings /10 on how satisfying the angst is:

》9 - 10: Will make you both angry+satisfied.
》6 - 8: Good, but doesn't DELIVER angst
》4 - 5: Disappointing. Scum didn't suffer enough.
》1 - 3: Cancerous material. Will lose brain cells.

Added really good "haha suffer more you piece of shit" novels with novelupdate links. Highly recommend u read them.
