I've Been a Teenager Since My Youth

Does anyone not believe in love at first sight? Lin Yan fell in love with Gu Ranran at first sight. He doesn't ask for anything in return for her kindness. It's a pity that their fate ended before it even began. It's the glitzy world between him and her. "I like you, past, present, and future." The early stage is lighthearted and sweet, and the later stage is bloody and cruel. Don't worry, the ending will be perfect in the end.
