You and I can't do this
- not exactly like unsleep bc seme isn't a typical loser personality/chronically sleep deprived (love both traits but this seme is not tht way) BUT he is pathetic for the MC like he genuinely can't live w/o him by the end
They really are rivals to lovers (like acc, not enemies to lovers more like unsleep where they just don't rlly like/care for e/o in the beginning), the seme is such a likeable, competitive non-rapey dude who is so adorabl-y smug like he goes around saying o I won't like this person ever but then falls madly in love, lastly it's the I promise not to fall in love w u ,(but then mutually fall in love) trope. Best part is plot progression bc then falling in love makes sm sense + doesnt come outta thin air yk? Like its so so good, highly recc
any not popular mainstream manga/manhwa like unsleep where they kinda dont like each other but somehow find themselves getting freaky and when the ml keeps getting carried away even tho he doesnt like mc
