Boku no Kawaii Yopparai
Not very explicit smut scenes. And the relationship develops pretty quickly. Still is good and it's short, sweet, and to the point.
Usotsukiyachi no Nagai Yoru
Im so confused about how this is the end. Like no final confrontation? They got their happy ending but I wanted a more solid front and a final confrontation for the couple. It kind of annoying but it was so good that I couldn't put it down. The drama was amazing, but the climax left much to be desired.

Its a little confusing about what's going on some times but the general storyline is good enough.
