fuck it I’m throwing this one at you because I love it so much and it’s actually pretty new and deserves way more love

it’s 75 chapters atm and ongoing
to summarize, mc works in an office and is very popular with his co workers and admired while also seen as perfect by them
however, he’s actually a narcissist playboy behind the front he’s putting up
in his private life outside of work he’ll hook up with guys and go on dating apps and so on but cannot find love no matter what (while also being a judgemental asshole himself who rates his own hook ups)
however! everything changes when he meets the ml who’s a co worker but also his polar opposite with the two going on a work trip that results in them sleeping together and making a deal that if mc doesn’t fall for ml they can keep sleeping together
genuinely? mc starts off as a yellow flag but my god he has character development and becomes so sweet to the mc but still relatable as hell without ripping away all his personality
yes there’s an anime adaptation of 8 short episodes which is just the first minor part of the manga (god I love the dub) with the sex scenes included (uncensored version for the win!) alongside the recently confirmed live action adaptation which I’m not sure if it’s out yet

Is there a yaoi where they both like each other, but then because of a misunderstanding or something, they didnt know? :3
