[S]toryline:

People might say that age is only a number once you’re in love with somebody. But for Eunmi, it was a principle that she used to refuse to ignore. For her, an older guy is important because she herself wasn’t the kind of mature and independent girl that didn’t have any problems with dating a younger guy. She wanted to be spoilt by her boyfriend, not to spoil her boyfriend.

All her self-principles broke down once Hwang Minhyun came into her life and took that special place inside her heart.

She fell in love with his kindness.
She fell in love with his angelic smile.
She fell in love with his gentle attitude towards women, especially the ones important for him.
She fell in love with his hardworking personality.
She fell in love with him and his beautiful soul.

But unfortunately, now this angel in disguised lied down with no energy, body temperatures rised up and burning forehead. He collapsed from his long exhausting schedules.

"Yeah. He came first. Whether I’ve studied enough or not, I should be beside him."
