Dating your friend's brother, actually the beginning of this's because your friend sold you to her brother, she set you up with him, his love for you's sincere, no matter what your shortcomings or your physical appearance

He never told you about his illness, until his illness relapsed and he was admitted to the emergency room, you didn't even know he was in the hospital

The next morning at school, your bestfriend tells you that he's in a coma, you are depressed and your bestfriend tries to cheer you up, during after your bestfriend calls her male friend to check on Elwin's condition via your phone, upon arrival at the back gate of the school, her male friend told her that he had not realized before, still 2%, you're a little relieved and part ways to go home from school

You think about him continuously, until there's bad news, Elwin's declared dead your bestfriend said, before he died he wrote his last letter via laptop, that says:

"If you see this, that means I'm passed away. sorry I didn't tell you before. take good care of yourself, don't damage yourself. and I'm sorry I can't look after you anymore. if I enter your dream, it means I have the opportunity to meet you, even though in the end you wake up. make yourself happy, whatever it takes. and last.. don't cry for me, okay?"
