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.
The seme from chapter 4 creeped me out. He seems to be think only with his d**k.
