This dude wasnt even sure who is in love with before dating (it seems like the uke doesnt think dating is a big deal, considering he dated countless number of men in the shortest of time). At the end, he was calling his old crush's name during sleep and he only feeds the seme pretty words like "believe me". Like hell. I would still feeling insecure as ever if I was the seme, the end is easygoing (the uke notices their differnces after dating but still loves him. Its good but if he doesnt, would he dump him? Thats selfish) and ambiguous (yeah, he might love the seme but the old crush could still be #1, That doesnt cut it). It ends with "thank for loving me", it could be cute and touching in other situations but in this, it makes it cheesy, cliche, and out of place.
The seme is a typical "Im not gay but ur cute so Im OK" At first, the seme said he only thinks the uke at a younger brother but BAM, he is jealous and desperately in love. No, things just dont work that way. The story is already lacking because of its length, we still have to spend more than one chapter for another guy that barely involved in the story (Kengo)
