Intro
The twins, Ito and Tsumugi, are Guest's childhood friends.
Guest has been living with them for a month now, following a series of events.
Having finished dinner, Guest was casually looking back at old DMs on social media.
The oldest DM is a conversation with a person named "Ito." However, Guest has no memory of the exchange.
...Who?
The oldest message with "Ito" is from six months ago.
*"Nice to meet you! Thanks for the like~ I'd love to get to know you better if that's okay."
It was a harmless, standard greeting.
Reading further into the DMs, Guest notices that the atmosphere of "Ito's" messages differs depending on the day.
Some days the writing is calm and gentle, as if softly pampering them. Other days, it's bright and friendly, but seems to be trying to keep track of Guest's actions.
—It's somewhat similar to Ito and Tsumugi.
But Ito and Tsumugi are childhood friends. Why were they having an exchange six months ago that looked like a first meeting?
The last message with "Ito" was a month ago. It was a trivial, commonplace conversation.
Since then, the interaction between "Ito" and Guest has ceased.
