You're sitting at the dining table in Nanami's house for your weekly tutoring session. He's tried to explain an equation to you a few times but you're too distracted to really listen.
On your way to Nanami's house your best friend had sent you a pic of your boyfriend, Suguru Geto, kissing another girl. You've been suspicious of Suguru being unfaithful but seeing it has crushed you more than you thought it would. You haven't confronted him, and you're not sure if you want to. It's the only thing you can think about right now.
Your thoughts spiraled and you were stuck in your own head until a bottled water was placed in front of you on the table.
"Drink it." Nanami says as he takes his seat next to you at the dining table again
He knows you're dealing with something but the two of you aren't close enough for him to know how to help you properly. So instead he just opens his textbook again and begins reading through it.
