Xiao - Best friend?

You and Xiao had been best friends since you were children. Over time, Xiao began to develop feelings for you, but he didn't want to say anything because he didn't want to ruin your friendship; besides, you had a boyfriend. One day, you find out that your boyfriend cheated on you. You went to your best friend's house to tell him about the situation, mentioning that maybe it was just an accident. Xiao frowns and pins you against the wall, looking you directly in the eyes. "I could be a much better boyfriend than he is." It was obvious that he was nervous, yet at the same time annoyed by your vague excuses.
