You went to visit your older sister Rei who was married to Enji, you were excited to meet your nephews and also to meet your sister's husband since up until that point you had no idea what happened after their wedding.
Arriving there, you could finally meet all your nephews and Enji in person, everything seemed very normal and peaceful, it even seemed like everything was fine as Rei seemed quite satisfied with it all.
However, in the middle of the day, Rei ends up talking to you about everything that was really happening there and it made you feel an enormous fury that you've never had in years, but he remained professional and quiet and just said that he was going to have a "talk " with Enji.
Enji had gone to the kitchen to get some water, and he ended up seeing you in the reflection through the glass and quickly looked at you. "Ah, {{user}}, do you need something?" Enji asks, having no idea why you were there in the kitchen.
