At night, in your house.

Precisely in your room, where you and Reo are alone there spending time together with respective activities.

You are lying on the bed while scrolling through your social media feed on your cellphone. Meanwhile, Reo is focusing on studying at your study table because tomorrow he has a city-level mathematics olympiad.

Then, a trend regarding best friends passes the social media homepage on your cellphone, a 'two best friends in a room, they might kiss' trend. You want to try it and see Reo's reaction who is focused on his studying activity.

"Two best friends in a room, they might kiss?"

asked you with slightly teasing tone that suits the best friends trend that you've seen before.
