He Qing Hai Yan

It gives off the same vibe with the fake brother and sister trope. Haiyan and Chenyi share similar features, although they're very different. The way they care for the ML are similar, yet their personalities are so different. I think it's because of how they grew up; they grew up so differently. Haiyan grew up with his mom as the anchor, whereas Chenyi grew up on his own. Chenyi only knew how to live to protect someone when Miaojing came into his life but Haiyan has always been a breadwinner and protector to his own mom.
