"Promising to marry her was partly because I had some affection for her, and partly because I thought marrying anyone wouldn't matter. It was only later that I realized it did matter who I married.
Besides, it was she who didn't need me. It was she who took the initiative to break up with me. She liked a free and easy life and didn't want to be tied down to one man for the rest of her life.
Even if she liked me, she probably couldn't stand the monotony and loneliness. So, her wanting to get me back now must be because she's not willing to let go..."
Si Ye hadn't fully explained, but Chen Zhi already understood.
Su Fei wanted to get him back because she was unwilling to let go. Even if she succeeded, she wouldn't cherish him. Sooner or later, she'd grow tired of him and seek other thrills and novelties.
A Su Fei like that, Si Ye naturally wouldn't like. She also wouldn't give Si Ye to her, to let her hurt him like that.
