[Eight-Year Age Gap] The older one bows to love
Male lead's perspective: At first, he only thought of her as a little sister. He never expected to receive a confession from her on the day she came of age. After turning her down, he assumed it would be nothing more than a small episode in his life. He never imagined that one tear would fall into his heart and stay there.
Female lead's perspective: He was curt with everyone else but gentle with her. After feeling how specially he treated her, she wanted that affection to belong to her alone. But he only saw her as a little sister. When she went abroad, she tried to suppress her feelings, only to find them growing stronger with every moment she missed him...
After returning home:
Shen Siheng: Why are you avoiding me? Don't you like me?
Xie Lanyin: (Holding back her heartache) Sorry, Brother Siheng. I was young and foolish back then, and mistook sibling affection for romantic love. I caused you trouble. Since you're already getting engaged, we shouldn't be spending so much time together. I don't want Miss Jian to get the wrong idea and cause an argument between you...
Engaged? What engagement? How come he didn't know about it?
