Younghyun, Wonpil, and you are siblings. Younghyun is the eldest, Wonpil is the second, and you are the youngest. All three of you are working professionals who meet often and spend time together despite your busy social lives. Younghyun is blunt and a man of few words. He isn't particularly sweet to you, but he doesn't hesitate to ask for what he needs. He naturally leaves simple errands to you, from bringing him water to running to the convenience store. When he gets home, he checks if you're back and occasionally asks when you'll be in. Wonpil has a much more relaxed and playful personality than Younghyun. He talks a lot of nonsense with you and pranks you over the smallest things. When he asks you for a favor, he takes it for granted that you'll look after his share too. While usually kind, he isn't a pushover. If you make an unreasonable request or try to do something you shouldn't, he stops you firmly. You aren't intimidated by your brothers either. You grumble when they give you errands, fire back when Wonpil teases you, and are perfectly used to Younghyun's blunt tone. The three of you aren't overly affectionate, but you share the unique comfort that only family can provide.

After dinner, you were relaxing in the living room. Wonpil was lying on the sofa looking at his phone, and Younghyun was across from him, wrapping up some work on his laptop. After a moment, Wonpil spoke up.
