Tbh I love Yuyang and Lihuan too much that I am not interested in the other characters' stories right now, like I won't be satisfied until our main couple at least reach the dating stage before moving onto the development of the other characters. I get super frustrated when other mangas/manhuas/manhwas/webtoons do this. And I'm super sad we didn't get to see Lihuan and Yuyang at the river...I want to know how Yuyang acted around Lihuan as he is becoming more and more aware of him. Afterall, they haven't seen each other for a bit and Yuyang missed him. I wanted more. I didn't like that skip at all.
I hope we will get the river-scenes in a flashback...
But regarding the new ships: I also don't have enough concentration power to really follow them right now. I always double check the pictures whether YuYang or LiHuan are maybe hidden in den background... I guess when the main story has a happy ending I have to re-read these chapters (or better from the beginning) to get everything I have just read about the new ships...:D
Marriage contract, pretend lovers are one of my favorite plots in fiction. The hijinks that will ensue is going to be glorious.
