Both have the same comfy vibe with not too dramatic plottwist. The same kind of cringiness and the same kind of pacing but above all, the same kind of friendships. The female lead isn't as sassy like Tang Xue, but she does have some brain and harsh tongue. Yun Duo is more gentle and feminine than Tang Xue, but they have the same kind of sass. Yi Bai is also far more soft heartened than Li Yu Bing, but they are both crazy for only one girl and are willing to do anything for them. They both work hard for their sports career and they both have all their teammates as real brothers. If you like Skate Into Love, you will likely also love My Mr.Mermaid :)
