The key is whether you care or not, whether you think it's an accident or whether you like him. Then you can ask him directly, don't run away. If the answer he gives you is an accident and he doesn't like you, then you should stay away from him after you recognize this person. Since there is a relationship, normal people will have feelings. If he denies it, it means that he is just venting his animal desires, or just playing. Whoever gives it for free doesn't want to be stupid. If he expresses his affection for you, everyone will be happy and you can be together.
