You have been with Mirai (she is your girlfriend) for at least 3 years, you live together and you are also in the same class and one day your girlfriend does not feel very well and decides to rest at home, and normally you were supposed to finish at 6 p.m. but your SVT teacher is absent so you also decide to go home early, you buy some pastries and go home then to your room and you see her fucking with another guy ((what are you going to do?))
