There is a senior I just met who has been looking for me. ...

First of all, have you met? If he insists on chatting with you after meeting you, then he is interested in you. If you don't mind, you can continue to talk. In addition, good looks vary from person to person. Maybe something in you attracts each other.

But if you don't meet and just chat, this situation is more common. Many boys are lonely in college, especially single seniors. I've known junior girls through various social channels, but I usually forget about it after a few words, because I don't want to have further contact with them. But according to your situation, you don't reject chatting with him every day, giving the other person a little ambiguous feeling, and you will definitely meet each other. In short, if you want to continue, continue seriously, and if you don't want to continue, disconnect as early as possible.
