Well, I'm Korean so I could read what it said on the cellphone. (You were talking about the part when after she died her brother gave away the phone, right?)
Well, on the screen of the phone it said "Sung-chan ee".
And the "ee" part is only used for people you are actually familiar with or close to. In other words, considering how Seh-wah didn't really care about anyone else but her brother, it proves that she was probably in love with him or something close to that.
yo. i really like this manga but i don't understand the cellphone part, you know at the end.
