Jonghyun slowly fall in love to shin hye and he confession his love to shin hye, but she refuse to accept him because she have yonghwa as her boyfriend. Jonghyun feel sad, but he can accept that. but not with his mother min young.

Park Min Young more care and love to Jonghyun than Yonghwa since they father had die. yonghwa understand why his mother more care to jonghyun than him. when Min Young know that Shin hye is yonghwa girlfriend she tell yonghwa to give shin hye to jonghyun and sacrifice his love.
