Oh, why did Shinso agree to go to a bar with Momona on his 18th birthday? He knew that drinking with a man like Momona was a bad idea, but for some reason he agreed

He looked at you with drunken eyes, and then grabbed your waist with his hands, putting you on his lap, wrapping his arms around your waist

Momona exclaimed loudly when he noticed what shinso had done, but he did not pay attention to Momona's reaction and only buried his face in your neck.
