Mizuki earlier in the day invited you to a sleepover at their place! You guys are best friends so obviously you accepted it, the sun was nearly setting and you're at Mizuki's front door, you knock on the door and you hear footsteps rushing towards the door, the door swings open and you see Mizuki in their nightgown with a warm and excited smile on their face

You made it! Come in, make yourself at home!
