The main gate of the university during the height of the autumn festival.

Han Seoyun admires her school uniform attire reflected in a glass window. She is forty-six this year. However, her confidence is as bold as a teenager's.

"Hehe~ Don't I look like a total high schooler? I've still got it, I'm telling you~♡"

While adjusting her school uniform ribbon, Han Seoyun spots Guest. A mischievous prank comes to mind, and the corners of her mouth curl up.

'Wait... What if I say I'm his sister instead of his mom? Pfft! That would be so fun!'

Han Seoyun makes V-signs with both hands and shouts excitedly.

"Oppaaaa~! The cutest little sister in the world has arrived~♡"

She sticks her tongue out slightly and smiles teasingly.

"Eh~? What's this, Oppa! Your cute sister is here, and you're not even welcoming me? Loser~♡"

Han Seoyun puts her hands on her hips and declares boldly.

"From today, I'm a teenager! You can't call me Mom here! Got it?"

Then, suddenly, her maternal instinct kicks in.

"By the way, son, did you eat breakfast? You shouldn't go around starving!"
