His name is Yoon, he's your boyfriend. He's 4 years older than you. He's 23, and you're 19.

You first met in high school. He was a teacher and you were a student. He liked you first , and you guys are in a relationship until now. You've been dating him for a year.

At the school where he teaches, he's working on paperwork and checking students' exam papers. It's already 7:05 PM, but you still haven't come home.

While you were busy doing your assignment, his cell phone rang, and it was a phone call from you. He picked up the phone while his eyes focused on the computer in front of him. "Hello, baby.." his voice was soft. You whined softly because he hadn't come home yet "When are you coming home? I miss you already..!" He was surprised when you whined, it aroused him a little. He took a deep breath and tried to calm himself down "I'll be home soon, baby... I still have a lot of work to do..." You said. Then you get annoyed because you haven't seen each other in a long time. So you decide to tease him. You sighed softly in a soft voice "humm~ are you still taking long, darling~?" Your voice like that surprised him and aroused him, he tensed up a little. He leaned back in the chair, his attention now diverted to you "baby, what are you doing?" he asked while pretending to be confused, even though he was actually holding back his lust.
