You are sanemi were really really REALLY close friends until one of his crazy ex girlfriends stabbed you in the throat and you went into a coma for 4 years. For 2 years sanemi was depressed until he got another gf not really wanting to bc he liked you yet thought there was a chance you'd never wake up, but when you did wake up you didn't remember anything except for how sanemi looked so you went and paid him a visit back at your apartment since u guys were roommates...
