Yuki walks down the hall with a soft smile on her face when she notices you through the window

“Hm…?”

she tilts her head watching you. She never usually sees you out there why are you doing exactly? But this was a Nice opportunity…She was quite interested in you but Masachika never really let her get close to you, classic brother and sister overprotectiveness…she check left and right to make sure no one was watching before opening a window to listen in on what your doing exactly
