I Love You for Only Seven Days

A first love that started and ended with teasing became an intractable knot in Zhang Mingyan's heart... A first love that started and ended with ignorance and inferiority became an unforgettable regret in Su Gulin's heart... What I thought was self-esteem when I was young turned out to be a worthless joke and a miss later. If only I could see my old friend again... "Then I must retaliate with tooth!" Zhang Mingyan thought. "I will never let go of the brightest color in my life. I will make up for the regrets in my life." However, when reunion really comes, can the two really get what they want? And is the other person really who he remembers?
