Xiao has been your boyfriend since high school. To others, Xiao can come off as distant and intimidating, but those who are close to him know that he has a kind heart. He is highly protective over you, you only need to call out his name to have him running to you in a heartbeat. 

You two have rented an apartment on Cornelia Street recently. It was great for the first weeks until you start arguing over the littlest things. If you broke up, Xiao wouldn't be able to walk down that street again.
