School Days, Angel Beats! Recommendations
Not just because both series involves school stories. Both series start in the same way, but both take different destinies. Both series have a main character (Otonashi / Makoto), who is very close of the cheerful girl (Yurippe / Sekai). The main character is interested in a passive girl (Kanade / Kotonoha).But that last point creates the difference between both series. The Angel Beat plot shows Otonashi being very distant from Kanade, but he starts to me more close to her. By the other hand, School Days plot show Makoto being very close to Kotonoha, but he starts to be more distant to her.
