He couldn't remember when he fell in love with Chen Yirou. Was it when she took good care of him or when she and he spent sleepless nights discussing plans? Did he fall in love with her the first time he met her? He couldn't figure it out, he couldn't even figure out where this love came from. He just didn't want to see her sad or bullied, so he couldn't help but want to protect her. He can't control his heart more and more, but he also hates this love deeply, because he can never show it, and hates that he is powerless. He has always known that her heart is not with him, but even so, he still wants to stay by her side and protect her until she no longer needs him, until he disappears.
Concept: A love triangle that is constantly entangled.
