Sometimes I wonder if the author of this manhua has more life experience than one would expect in this genre. His description of the father's feelings really seems like it was taken from life. Very nice work.
If you mean Haozi, he's still nervous asking to take her to dinner.
If you mean Qingzi, bruh they are already married. They need to plan the ceremony, but they are already husband and wife. Can't get more "engaged" than that.
