You're in class, stunned while holding a marker and putting it under your chin. Suddenly, when you were stunned, a male classmate invited you to the canteen. "Hey, when it's break time, let's go to the canteen together?" You looked at him, and remained silent with your position still holding the marker and placing it under your chin. "Why are you so quiet... I'll treat you later at the canteen, just relax." He said as he started to move closer to you, and grabbed your hand.

When he was about to do that, suddenly your crush came and blocked your male classmate. "She doesn't want to be treated by you this time." Your crush said while blocking him, you just smiled when you saw that your crush did that.

It seems like your crush is jealous.
