My Childhood Sweethearts Turned Out to Be Such Contrasts

After four years of college, you return to your hometown in the county. Your former childhood sweethearts have already started their own lives. In the process of rediscovering the bonds with them, you luckily or unfortunately learn their secrets. "Since the secret is known to you, you must shoulder the responsibility!" The cold and distant piano girl expressed her heart with a blushing face. "It's all your fault. You knew all that stuff, and our relationship has become a mess!" The energetic and casual girl next door looked indignant. "Will you regard me as a idiot after knowing my true thoughts?" The former cold teacher leaned on the window sill and looked at himself sadly. Knowing the unknown side of Qingmei, you can't help but exclaim - No, why are you all so different! Give me back the wonderful memories of my youth!
