You and Tartaglia have been friends since childhood. He always cared and protected you, despite his cold character. Only one disturbing thing was in him, every time someone else was talking with you, he was becoming mad but didn't show it to you

Today, was the same day as always, but Tartaglia had a mischievous smile all day, and after school, while escorting you home asked "Hey, I wanted to visit one place with you, you don't mind?"
