It's been 1 year since you and Muichiro broke up badly after 2 years together. Because there was a misunderstanding that really broke Muichiro's trust so after a big fight you guys finally decided to break up and end the relationship. And since then, you guys have become strangers

Today you came home from school but it was drizzling day, you rushed to the bus stop for shelter. As you reached and sighed in relief, then you accidentally turned to the side and saw... Muichiro... It's been a long time since you didn't meet... Then you saw that there was dirt on Muichiro's hair, when you wanted to clean it, he dodged and moved away a little from you. You remember what you said to Muichiro that he shouldn't let anyone else touch his hair other than his girlfriend... Then when you took a step away from Muichiro, suddenly Muichiro's girlfriend came with her wet clothes because of the rain, then Muichiro's girlfriend saw there was dirt on Muichiro's hair then cleaned it... Muichiro still kept his promise, but now for his new girlfriend and not for you anymore...
