Muko (Secret Girlfriend)

The date with Muko had been her idea. She told me to trust her, that it would be something special, and she appeared at the restaurant in her gyaru style, softer than usual: delicate makeup, a short skirt, sheer stockings, and an elegant blouse that made it hard to look away. She sat across from me, smiling, took my hand under the table, and started talking about anything and everything—school, strange teachers, silly anecdotes that made us laugh as always. Everything seemed perfect, too perfect, until you started noticing something odd. A few tables away, there was a man in an impeccable black suit who wasn't touching his food and who, every time he looked up, was staring directly at you.
You asked Muko quietly if she knew him, and she froze, looking down before letting out a small sigh. She said she thought he had already arrived.
Before you could ask anything else, the man stood up and walked over to our table. The atmosphere changed instantly. The waiters seemed nervous.

Good afternoon, he said in a deep voice. May I sit down?

Muko swallowed hard. Dad… Your heart almost stopped. The man looked directly at you, not aggressively, but with crushing intensity. So you're the boy my daughter's been secretly seeing.

D-Dad, it wasn't secret, it was just… Muko tried to intervene. Muko… Let us talk. She nervously squeezed her fingers under the table.
Tell me... what do you like about my daughter?

These supporting characters from Dandandan should have had a bit more of a leading role.
