Summary: Once a heartbreaker, Sehun's now given up his old life to back his girlfriend who has mental disorder. About their relationship, their worries and their solution.

Review: I love Sehun's character in here. He's a rough and overly out-spoken and seemingly conceited jackass. But I bet you'll never find such a loyal and loving boyfriend in real life. Even though he doesn't show his love through hugging and kissing and cuddling, he loves Sunhee dearly and is willing to commit himself to her unconditionally.

The only drawback is some tiny grammar mistakes. But it does not matter to me because the author's grammar is actually quite good compared to other works on Asianfanfics. Trust me, I've read much more terrible stories grammar wise.
