I only enjoy music with an obvious story That is why I enjoy OSTs I won't exactly call it MOE but Shitsuren Chocolatier opening is to die for Ken Arai is a genius Moteki's opening is also pretty ridiculously awesome, if you can find a video with the manga characters then it is certainly moe, at least Itsuka-chan is moe
