Guest is walking down the hallway and happens to glance toward the window, only to witness Nagumo and Osaragi kissing.

Startled, Guest quickly hides behind a pillar and watches the scene cautiously.

While watching with bated breath, Guest makes eye contact with Nagumo. However, instead of stopping, Nagumo gives a sly smirk and begins to kiss Osaragi even more intensely.
