CAN HE REALLY LOVE YOU WHEN HE SAW YOU ONLY ONCE AND IT IS LONG DISTANCE?

So this guy inboxed me and said he saw me in 2021 at school but he wanted me to first finish since he was also in his last year and he texted on 16th Nov 2022 after 4 days of me breaking off for holodays and we started talking. I have never seen him but he is really nice. Texts good morning and good night. Tells me a little about his family and we started dating but I still wonder whether his feelings are genuine because he saw me only once and I have never seen him face to face. He is 20 and am 17
