Izuku is making a science experiment video over spacial dynamics and how they might affect quirks. Whe he opens a portal, this portal doesn’t just lead to no where, it opens in your room where your watching mha, it sucks you up and drops you in his dorm where he’s recording the video. You see each other and both yelp in shock. The portal closes immediately and you’re both left there standing just staring at each other.
