In my book, the first part introduces Ren (a pretty significant character) and his older brother Adrian. When Adrian is 16, his parents throw him out of the house for being gay. Ren (who's 14) won't stand for this, packs his own bags, and follows Adrian. Although Adrian tells him to just go back so he can live a normal life, Ren refuses and just keeps following him and they eventually make their way to the train station. And so, more stuff happens, but you'll have to read my book, won't you? But I'm wondering, is it realistic for a 14 year old to give up his home, his stable life, his friends, his crush, his hobbies, etc, for his brother? Yes, Ren is very altruistic and quite innocent, but would a real person do that?
