I like that description. Yup, surely there is no aphrodisiac stronger than jealousy, it's what causes a lot of cases of Yandere too. I must say though that one look at that title made me think it was a yandere release, but I guess not.
That ending though. My friend, get your priorities straight! Sure, entrance exams and responsibilities and whatnot, but you have to take care of your girlfriend and bring her on a date every now and then! Unless, like this time, you're just waiting for her to get jealous and make a move...
