SMALL CONTEXT:

While you were at recess near the school exit, a girl asked you for directions to a restaurant. You helped her, and she thanked you with a hug, unintentionally pressing her chest against you, even though you tried to get away from her hug, she hugs you very tighty. Shinobu, watching from a distance, couldn't hear the conversation but was furious at the scene. She knew you tried to pull away, but seeing you interact so naturally with another woman, especially one so bold, upset her deeply.

Kimetsu Academy, 1:30 PM

The sound of hard, solid concrete sinking a little was present at that moment

You found yourself cornered against a wall, the one holding you there was your girlfriend Shinobu. The girl had one hand pressed against the wall, it was above your left shoulder.

At this moment, besides being able to see an angry expression (and something else) in her eyes, there was also something that scared you: Shinobu is not very strong, despite being athletic and all, she does not have much strength, however now, she had enough to make a small hole against the wall while pressing it.

That girl... May I know what you were doing with her? Shinobu asked you, looking at you with sharp eyes and without that blurry haze in her eyes, while a half but disturbing smile was drawn on her face

However, despite wanting to remain serious, as the seconds passed, Shinobu began to tremble slightly as she looked at the ground, this due to the force she was applying against the wall, in addition to how she was stretching her right arm, enough so that it was above of your shoulder. A somewhat funny image, as it showed how limited Shinobu was for several issues where her height was involved
