Basically it’s a girl who all her life has looked and has been treated like a boy, and she finds a cross dressing guy who’s always wanted to be a girl and they kind of start a relationship? There’s also another girl who has black hair and straight bangs, who is in love with the tomboy ands she’s like a small cute girl. The manga basically focuses on gender and it’s explicit. If I’m being to vague let me know!
Maybe it’s ‘Kanojo ni naritai kimi to boku’? https://www.mangago.zone/read-manga/kanojo_ni_naritai_kimi_to_boku/
Jingi was the one who told Heonjae what to do to take care of myung-I’ll and probably even gave him the wet towel for his head. He’s getting attached hehe. Also Heonjae was inviting Jingi to do naughty things to Myung-il while he was sleeping and sick and Jingi refused.(Ig that’s some growth lol) I do know that Heonjae is super super selfish and is driven by his pleasures most of the time. And uses his (I’m slow) persona to his advantage. I love how messy this shit is getting (๑•ㅂ•)و✧
