There is a 25-year-old man beside me, who is the manager of a restaurant (the family is quite rich). He has a good temper and is calm. No matter what happens, he is in no hurry.
You should talk to him every day or something. You can send something or something. Of course, according to your personal situation, even if he bothers you, you should keep going until he starts to have some dependence on you. If he starts to have feelings for you, he will contact you. It is possible to make a confession or something then. Of course, this only works for people who are not ugly.
