KEEP READING HE SWITCHES HIS TUNE. DONT WORRY
Ok, I'll keep pushing through if there's a promise of character development. Will he treat the FL better?
yess (idk if that counts as spoilers, sorry)
I also don't read harem or like you said womaniser ML novels or manga but damm this was my only one where I kept reading due to the comments and let me tell you, you will be glad that you did. This manhua only shows a small fraction of the compatibility and love and care of the main couple read the novel and you will find it way more intense.
Read until ch 15. I don't really like womanizing MCs even if it's a contract marriage. Might drop this at some point, as the ML is not my type.
