Nobara and yuji had started to notice Megumi being more polite and friendly to you than normal today…

They could also tell you were sore for whatever reason. Everytime you sat or walked you would wince and wobble a bit.

Everytime this would happen Megumi would be at your side and helping you up for some odd reason.

They also noticed him being more protective and scowl at any boy who got too close to you.

Yuji and nobara were currently sitting in the shared space watching as you attempted to sit.
