from that night cho hee always called jinwoo. since then he couldn't help but feel exited to hear her voice before he fell asleep.
she didn't only help him falling asleep without crying, but also brightened his mood.
suddenly the world wasn't just black and white anymore.
cho hee loved talking to jinwoo. it's not like she wanted to help him because she pitied him, but because she liked him as a person.
through all this time they became very close, even though one of them was rarely ever speaking.
