Help Me Find This K-Drama Please

Hi everyone,

A few months ago i saw a show about a teenager father who is a high school student. I saw its page on MDL. He is becoming father and don't know about it. Mother leaves baby to him and he is trying to deal with it. This is what i remember but i can't find the show. Any idea? 

It was an old one i guess.

Maybe, Rosy Lovers, but they were college students and aged around 20. 

Baby and I was the movie. I remembered it as series. Thank you. I'll check Rosy Lovers too :)
