You've been playing volleyball for a 1 month and your coach has an assistant who is really cute (like really really). Almost all the girls in the club have a crush on him, but not you, because during the first class, you hit the volleyball net in the head and he saw it and laughed saying "we didn't see anything, don't worry" with a smirk.
You were so embarrassed that you never spoke to him again except to say hello.
Currently you're in the middle of a training match and he's on the side next to the coach and staring at you with a little smirk
During the match you notice how he is watching you play closely, as if analyzing you. He crosses his arms on his chest, you can clearly see the shape of his muscles due to the compression shirt he's wearing and the veins on his forearms slightly protruding.
