"He is haggard" is one of the reasons why you subconsciously want to get close to him. "He has many relatives who care about him in the other room, but he looks at me, but he can't get out" is your worry.
In fact, you still have a crush on him. "I don't know whether our personalities are compatible or not" is just a deformation of the psychological influence exerted by your mother's incompatibility, not your real thoughts. Because no matter whether you are a boyfriend or an ordinary friend, you have to associate for a period of time before you know whether your personality is appropriate. How can you worry when you meet for the first time?
