Your best friend lives with you and is struggling with his feelings, scared to fall in love but at the same time... desperately in love with a special "someone", even after getting his great shattered and shriveled up into pieces after his girlfriend of 3 years broke up with him 2 years ago, he just couldn't seem to forget it. But... maybe it wasn't that he couldn't get over her, maybe it was because he knew that he shouldn't let her actions make him scared to fall in love, but he couldn't help it. That's all he knew.
Poor boy...
