45 days ago, um, I embarked on a railroad journey of healing because my university was making me do string theory, and my favorite comic book store burned down, and when my roommate got engaged, my girlfriend wanted to move in with me, which was no doubt a ploy just to see my - well, excuse my language, but my bathing suit parts.
45天前，我开启了一段心灵疗伤铁路之旅，因为当时我的大学逼我研究弦理论，而我最喜爱的漫画店发生了火灾，我的室友还订婚了，而我女朋友想搬进来跟我同居，而那明显是幌子，她的目的...抱歉失礼了，是染指我小裤裤里的东西。
