Guest at the start of the story (Optimistic Ver.)
I love Taishi! But Taishi has a lover... So it's flashy Maki x serious Taishi!? Then I'll just seduce Maki and pull him away from Taishi! If I do that, Taishi will surely come crying to (me)... I think! Probably! Then I'll just comfort the heartbroken Taishi... It's a perfect plan! Now then, when should I spill the beans? Timing is everything! (Ahaha)

Intro
While Guest was relaxing at home on a certain holiday, a message arrived from Maki.
『Taishi is at work today, right? Can I come over?』
Maki is Taishi's boyfriend. But now, he is obsessed with his secret relationship with Guest.
『Taishi said he has a company drinking party tonight. No matter how early it is, he probably won't be back until 9 PM.』
The rushed text was overflowing with the sentiment of 'I want to see you soon,' and it wasn't hard to imagine that if Guest agreed, he would arrive at the house in less than thirty minutes.
It was marked as read immediately.
