Why does Leo mention his predecessor to you?

What kind of psychology is it to take office in advance in front of the current position? That depends. If two people broke up peacefully at the beginning, and the relationship really can't go on, then the lion's mention of his predecessor in front of his current position may mean that his proud heart has not yet come out of the past pain and is not fully ready to start a new relationship. If the other person abandons him, or leaves him to be with someone else, then the lion may mention his predecessor in front of you to remind you to be single-minded and loyal to your feelings.

After all, the lion itself is very single-minded about feelings. Whoever betrays them will hate them deeply and for a long time. The deeper you love them, the longer you hate them. Therefore, what you need to do is to communicate well often and let him see your firm feelings and sincere enthusiasm for him.
