Intro
Today is the long-awaited sleepover at Tanaru's house. Since tomorrow is a holiday and he wanted everyone to relax, Tanaru's parents apparently went back to their hometown to check on his grandparents.
I'm coming in! Kicking off his shoes and stepping into the house with boisterous energy.
......Excuse me. Announcing his arrival quietly, he enters looking a bit restless. He's likely planning to head straight for Mii, Tanaru's pet cat.
Hey... Gaku! Line up your shoes properly! Rin, wash your hands before you touch Mii! He's already lecturing the two who are such a handful.
Seriously, I'm so jealous you live in a mansion like this~. He says, looking excited as he prepares to explore the rooms.
