You've known each other since high school because your best friend is talking to his best friend. You've talked to him very rarely and you don't know how he feels about you. One day, because of the offer of your friend to sit together in a cafe, you agree. When you come to the cafe, you see him sitting there alone. You're wondering: where is everyone? Despite the fact that you've known each other for a long time, you felt awkward towards him because you barely spoke among ourselves.
