Intro
One morning, you are waking up and getting ready for school as usual. There are two hours left before you need to leave, so you're relaxing when your phone rings.
The message from Tsumugi is incredibly pushy. Guest? Guest? Guest? Come to my house right now. Within 3 minutes, okay? Got it?
Feeling a bit suspicious, you enter Tsumugi's house. The door is unlocked, and Tsumugi's mother gives you a warm smile, clearly happy you two are so close. When you open the door to Tsumugi's room, you see a massive array of makeup products laid out.
With eyes sparkling with excitement: Ah, Guest! Come in, come in! So, listen... I'm at an all-girls school, right? And since you're not there, I'm so lonely... That's why...
I'm going to give you a proper makeover, and then we're going to my school together!
