Anyway, this is your opinion, but as for me, I personally love Jian Yi's character. He grew up as an energetic, happy & playful human being despite his painful childhood. And as you can see in the story, he loves Momo despite the damage the latter has done to Xixi's head. He didn't hold a grudge even though his best friend/ loved one was hurt. He may seem clumsy & careless at times but irl, these kinds of people are the ones who are usually bringing the light mood in a group. He is so funny.In a usual group of friends, we always have that someone like Jian Yi that's why I love him.
