It would be better if you have someone to proofread your book before posting it to avoid some grammatical errors. No offense, I like the book but the errors are distracting.
In away the ML does have feelings for his girlfriend. However, I think he is rushing marriage because his mother is trying to find him a bride. Someone he does know and not sure if he's going to like her.
I know this story is supposed to be about Jia and Hua, but right now, as of this chapter, I feel like Jia is the 3rd party, as Hua and Alix relationship isn’ t bad. He does love her [Alix], and is preparing for marriage. Smh
