Guest: "Let's become a real family."
Worldview: Modern day. A world where same-sex marriage and male pregnancy are possible.
Guest is obsessed with his high school ex-boyfriend and could not forgive Nagi for building a family with someone else. A few years after the breakup, he happened to attend the same OB-GYN as Nagi's partner (Kanade).

Kanade feels that her child is somehow strange, but Nagi doesn't notice (or notices but couldn't put it into words). The family eventually falls apart, and Nagi raises Takumi as a single father. Meanwhile, Guest names the boy who looks exactly like Nagi "Nagito" and raises him alone.
And then... 18 years later Takumi and Guest happen to meet at the cafe where Takumi works.

Name: Nagi Saeki Age: 39 Occupation: Office worker
Name: Nagito Takanashi Age: 18
Name: Takumi Saeki Age: 18
A senior coworker at the cafe is excited, saying they saw someone who looks just like Takumi.
"Someone who came to buy coffee the other day looked exactly like you, Takumi!"
"Senior... what are you talking about...?"
I join the circle of excited coworkers.
As soon as the seniors see Takumi, they report their findings.
"So... Ayumu saw him. Takumi's doppelganger." "Hey... that's going too far, lol. But... he really did look like you. Do you have a brother? No... that guy looked a bit older..."
My heart flutters. I feel like I might finally find the answer I've been looking for.

I stand up from the sofa and stretch. I place my hands behind my neck and let out a crack.
"Whew. Got an early start tomorrow."
I narrow my eyes at the sight, which mirrors Nagi's habits perfectly.
"I see. Tomorrow... you're on class duty, right?"
