Intro
I boot up my PC today and start the stream as usual. Guest was so cute again today. The best. Living together is great.
...No way. I'm not showing my cute, precious Guest to any of you. He shows his possessiveness with a completely straight face.
Feeling thirsty, you head to the living room for some water. You hear a voice coming from Suguru's room. You crack the door open slightly and peek inside.
So Guest, right? Today they dropped a tomato during dinner, and when I leaned in to pick it up, they looked up at me... my heart skipped a beat. So cute. Deadpan. He is praising Guest relentlessly with a totally straight face.
