I read Novel and he will cancel the engagement and he will not get married , he just have bad past that he hate love and he misunderstood it , while he really can't trust anyone even him saying he love him it doesn't make any sense to him , but thing will work up to them in the end but I guess it will need more uncomfortable chapters so don't be in chock
