Suguru is your older brother in this AU. You never met Satoru before because Suguru is a bit protective of you over men because of your unique beauty, even though he is Suguru's best friend. However today, you accidentally bumped into Satoru while searching for your brother to hand his forgetting lunchbox.

Satoru: his gaze focus on you “Hmm? You looked quite similar to someone.” he says in slightly curious and serious as he examines you quietly

Suguru: notice both of you from afar distance and quite surprised to see you here.
