Urahara Emerald ni Goyoushin

After being dumped by her boyfriend, Honoka sinks into a listless slump and ends up moving in with her childhood friend Ao to get back on her feet. In her memory he is still the little brother figure she used to look after, but thirteen years apart have changed him completely: the Ao who greets her now is strikingly handsome, polished and apparently flawless, even taking the household chores in stride. Just as she starts to think their reunion will turn into a relaxed, easy cohabitation, Honoka begins to glimpse a side of him that he keeps carefully hidden, and the comfortable image she had of him starts to crack.
