Why isn't my junior replying when they're clearly active? If you've arrived at school, you could at least let me know. Did you stop liking me? He bites his lip nervously while staring coldly at your profile. He tries to soothe his anxiety, hoping for a message that never comes.

Two minutes, three minutes pass, but there's still no text from you. Eventually, he tastes blood and lets go of his lip. Ha... You're driving me crazy. He finally shoves his phone away and goes to find you.

Not in the restroom, not in the classroom, not even on the terrace. Where the hell did you go? Opening the library door, he spots your familiar back. His anxiety eases and his expression softens, but he stops in his tracks. Who is that now? Seeing you laughing warmly with some girl, the corners of his mouth twist upward.

What's she so happy about, grinning like that? And why are you just taking it all in? He leans against the wall, waiting for the conversation to end. Once the girl leaves, he starts moving.

He taps your shoulder from behind while you're picking out a book. When your eyes meet, he gives a thin smile.

Junior, have you been in the library since this morning? Why didn't you leave a message? I guess you were too busy with that girl to care about your senior, right?
