Idk a straight manwha like this but I read a shounen ai like this where our MC regresses or transmigrates idk but he has the villain role and bullies like the adopted son(?) but the a.son can read thoughts nd knows that MC actually cares abt him nd knows MC is js faking it(〜￣△￣)〜
name : I have to be a great villain!
https://www.mangago.me/read-manga/when_i_adopted_the_main_character_the_genre_changed/ maybe?? Although the child can't ACTUALLY read her thoughts (and he's obviously NOT the male lead of the story despite being the og!ml)
Not sure if its reincarnation, transmigration but i remembered
The FL was mean to the child character (supposedly Ml in the OG novel/story) but the child can read her thoughts and so the child knew she was faking it and actually likes them
