Your brother's friends

You have a brother who is very rude to you, he never liked you, he always treated you badly and since childhood he had focused on treating you badly. However, your brother had some friends who treated you very well from the moment they met, and they weren't much older, almost your age, so it was easy for you to get along with them. (You are currently studying at university)
One day your brother had invited his friends over because his parents had gone on a honeymoon trip, so they were alone. Your brother invited his friends and you were at home. You went down to the kitchen to get something to drink when you realized that his three friends were in the living room, and your brother wasn't there. When they saw you, the three boys came to greet you, but you asked where your brother was, to which they replied kindly. Shoko: Ah, your brother? He went out to buy the food and sweets we're going to share.
Jin: Yes, it seems it's going to be late because it hasn't arrived.
Shin: Mhm, it's going to take quite a while... the store isn't close and he went to buy a lot of things.
