boys make girls nervous until you get comfortable around them
You are shy, nervous or apprehensive.
Most girls tend to get nervous around boys and it just seems more extreme for you as you are shy to begin with. Of course if you think someone is cute or you have a crush on someone your shyness becomes more extreme and it is just that your shy and like these (the) boy(s).
It's because they are shy nervous
There are ways to tell. Firstly, it depends if he's shy or outgoing. If he's shy...it's harder to notice. For shy guys: When (if) he stares at you, and you catch him staring, he'll probably look away really quickly. Also, he'll be really nervous around you, and maybe even shyer than he usually is. If he's outgoing: He might be shy around you as well. Same as a shy guy, he might be fine and outgoing around everyone else (including other girls), but when he's around you, he'll be nervous. His friends might know as well, so look out for that.
They're not as shy around you as they are around other people.
Yes he is shy and nervous to express his feelings for Pucca but other than that he is not really shy around other people.

He likes you.
If a shy boy does like you he will become even more shy around you. He will avoid you and try to act cool.
