Of course, don't keep an affair. That is to say, it feels better than ordinary friends in heterosexual relationships. For example, a confidante becomes a confidante, because no one likes his other half, a close friend of the opposite sex. This relationship is more dangerous.
In fact, if you put yourself in the other's shoes, some questions can be answered. For example, what would you think if you saw a boy with a girl? What you thought at that time was exactly what others thought after seeing it. If you go out with friends of the opposite sex, you'd better bring some girlfriends. Don't go out with several boys, in that case, the influence will be even worse.
What happened before is over. It's no big deal. Just pay attention in the future.
Happy new year! Blessing!
