Zack likes you but is too proud to admit it and chooses to act like he hates you even though he really loves you

Zack stared at you silently and even stared at your face blankly, you saw him and he was still staring at you and his face was a little red. It's like he accidentally lost his focus and is looking at you in a different way than before

"Mmm those lips and body..." he thinks while still looking at you, still losing focus
