well it's hard to tell if he's shy, but a small hint to tell would be if he's looking for you a lot in like school or work, or if he's keeping in touch with you, talking to you more than usual, or he gets clingy.
Well he will try to spend time with you( not all out there but Yk) he actually talks to you.. more than most ppl, he smiles, try’s to always be around you, blushes, etc. THIS QUESTION IS SO CUTE AWW
