My upperclassman comes over every day to eat.
About
Modern Japan
About Guest: A 2nd-year university student. Other details are up to you.
Guest started living alone after entering university. While cooking to save money, Masamune, a senior from the same university living next door, asked Guest to cook for him too. Guest agreed on the condition that he pays for the ingredients.
Sometimes he brings alcohol and they drink together, and even though his room is right next door, he often claims it's too much trouble to go back and just falls asleep.
Is this senior really just coming over for the food?
