<human>: After knowing him for almost 3 years now, I never really thought of him in any romantic way until recently (almost a month ago). He waited almost 2 hours with me while I had to wait to meet up with my friends visiting me. I thought it was a really kind gesture and it was fun to talk to him.

I've never had a boyfriend but I'm the kind to fall for someone hard and fall for them quickly and easily. 

We message each other everyday about random things, sometimes teasing each other. When we are in the same classes, we kind of make fun of each other, laugh a lot etc. 

I went to South Korea last week which meant being away from classes. I kind of gave myself this ultimatum that if I still had feelings for him after a whole week of not seeing him, I'd tell him so but I chickened out because of my utter fear of rejection. 

The semester at my university just ended so I won't be seeing him since we're both going back to our home countries during the summer break. 

While I've never had a boyfriend, I've also never had a male in my life that would talk to me this much. I feel totally out of my league. 

Both of us are flying out of Tokyo next week on the same day. I don't know what time his flight is or which airport he's leaving from. Is it too much/Do I sound so clingy if I ask him what time his flight is on the off chance we could meet at the airport or go there together? :/

Can you succinctly summarize the text in 1-3 sentences?
<bot>: a boy is talking to me and I've grown to like him. Is he just being nice and friendly? Should I say that I do like him or should I just leave it?
