What I really liked was how the characters were strong but somehow very delicate in a sense. However, Midorikawa manages to give it spice and get the viewers intrigued, eh heh heh. I hate yaois when they make the uke sound like a total girl and it gets REALLY boring after a while. Oh MAMA! You gotta admit that Souichi's 'voicing' is ultra hot&smexy. Just the right amount of it so the watchers won't get bored, and just the right amount of character development and storyline to keep it moving and interesting. Not too much sex, since that would be a buzzkill. The pace is just right, and it slowly shows how Souichi is accepting Mori into his life.
(Those who have already watched please continue, those who haven't please turn back now) Although, the 'forcing' isn't really extreme. NB: If you're against malexmale or any 'forced' sex then please refrain. If you haven't seen Koi Suru Boukun yet, GO DO IT NOW. It's a refreshing piece compared to all the cliche yaois out there, such as rich men buying poor helpless boys into being their sex slaves or school boys having twisted love triangles. Everything from the art to the sound was awesome. This is one of the best yaoi work I've ever seen.
