This was my first yaoi manga and anime. It always has a soft spot in my heart.
What I'm worried about now is the Ni-san. Misaki is his sweet younger brother and he is gay. How is he gonna take it? I hope he won't blame anyone especially Usagi and try to break them apart but accepts their love with an open mind. I'm biting down nails till everything is fully revealed and settled for good so they no longer have to tip-toe around and find excuses to live together. They fully deserve it.
I still think the seme ain't human, I mean very much possible. How did he bring back the Uke? The Uke had sleep paralysis too when the seme was enjoying himself... ٩(๑❛ᴗ❛๑)۶ and the seme was staring at the uke's neck in one panel http://www.mangago.zone/read-manga/k_s_secret/uu/d_chapter-10/pg-15/ hehehe all guesses.
Maybe I'm reading into it too much coz I'm obsessing over this manhwa ლ(´ڡ`ლ)Bdw it's so funny when the seme gets dark circles under his eyes..











Wait wait..... With that hand??? No no no no way, darling there's no way.
