After texting the wrong person by mistake, he finds himself falling for that person who types at the other side of the screen. Conflicted by his feelings, Myungsoo is trapped between a mysterious girl he wishes he could get to know but doesn't seem to have much in common with, and the stranger he has yet to meet in person but seems to think exactly the same as him.

The Characters

Passionate about photography, he dreams of making a career out of it and being able to support his family, since his mother had to raise him and his brother all by herself. Myungsoo is smart, very smart. Athletic, too. But what he's got in good looks, he lacks in social skills. He is shy, but inside that cold exterior resides a caring and warm person. However, girls don't seem to mind this exterior, considering how all of them swarm around him wherever he goes.

Every girl except Jieun.

Jieun is the daughter of the school's principal. Disgustingly rich and extremely beautiful. Despite not being the brightest crayon in the box or even good at sports, she's at the top of the social pyramid, fact that she could care less about. Everything else about this person remains a mystery, something that strangely enough attracts Myungsoo. Only talks when necessary and most of the time can be found sleeping during class, but there are no teachers who dare to nag her about it.

40- or at least that's how Myungsoo refers to her, is the girl Myungsoo once texted by mistake but never stopped talking since then. They call each other 40 and 50 respectively, the last two digits of their phone numbers. Her biggest passion is music and dreams of becoming a songwriter. She's too shy and self-conscious about anything that has to do with herself (looks, personality, talents) and has never agreed on meeting Myungsoo personally.
