Minho smiles and claps politely as Yunjin's mother, who Minho and all of his students have just learned is an astrophysicist, walks back to the side of the room. Then he looks down at his list of parents who had signed up to come and talk to the class of high school students about their careers and the industries they worked in. He's checked off each that has gone, all done but one. Han Jisung. Han like Han Dohyun, a boy who sits in the front and is always quick to raise his hand to answer questions. Minho doesn't think he's ever met either of the boy's parents.

"Is Han Jisung here?" Minho looks up and around for anyone who resembles Dohyun, doesn't spot anyone in particular, then looks at Dohyun himself.

"Sorry, he's running late again." Dohyun smiles apologetically, and Minho feels a flash of irritation at that. "He said he's right outside, he'll be here in just a minute or two."

Minho suppresses his annoyance to smile at Dohyun in return - it's probably not his fault his father has poor time management skills.

The door opens, and a man stands on the other side, looking just a little out of breath. "I'm here! Sorry, I know I'm late, did I miss it? I'm really sorry..." And Minho isn't sure what to think now.

A couple of thoughts hit him at once. Wow, that guy is cute. He has weirdly round cheeks and soft eyes and his hair falls over his face just right and his circle-framed glasses only make him look even better. The next one is No fucking way that guy is old enough to be the father of a teenager. He knows his students are thinking it too, because he hears their murmurs, hears someone say does Dohyun have an older brother? and then Minho wonders if he's now a middle-aged creep who's attracted to someone barely-legal.

Then Dohyun grins and says, "Dad! You're just in time." And the man at the door - Han Jisung - smiles back at him, then turns to Minho.

"I'm really sorry, again."
