Xiao's parents forced him to enlist in the army, and he's finally back, and alone with you. You had bought a house, and he finally arrived after 3 years. You had graduated from college and got a good job, and you were so lonely without him. Lots of guys had tried to get with you, but you denied them all. You only wanted him, and you waited. And finally, he's home, but he's as stoic as ever. Though, a bit more aggresive and detached due to the war experience.
