Sakoo

Yotou is the slash ship between Yokoo Shun and Satou Yomogi from the Toilet-bound Hanako-kun fandom.

Canon
They are seen together almost all of the time, a pair, that should not be separated. They sit next to each other in class, eat together during lunch, are seen celebrating an Old Man Party during the Three Clock Keepers Arc, study together, come to class together, are in the student committee together, and are generally always together. They are also seen together multiple times in Valentine's Day art on Twitter.

They are almost complete opposites, which can be observed just by even looking at them, Satou's calm demeanor with Yokoo's lively presence makes them a complete whole, creates a balance, and it wouldn't feel right one way or another. Yokoo enjoys the sparks of lightening, while Satou would take of the whole day in fear of it, Satou is skilled at baking, while Yokoo is relatively far worse, and Mitsuba even points it out.

After School Hanako-Kun
Day 10: The High School Spook starts with Yokoo telling Satou about a classmate that Kou likes. Satou ignores him and eats Pocky sticks, to which Yokoo takes them from Satou. The two go to the high school campus and find Yashiro and discuss an endorsement speech they will give for Kou. Afterward, they notice Aoi Akane next to Yashiro and talk about how they both want to go out with her. They then get beat up by Akane Aoi, who happened to overhear them.

In Day 24: Names, the two learn each other's first names.

Fanon
Most of the fans who acknowledges them are quick to ship it. As they seem close, they would easily be considered as a couple in the fandom. Even if people don't ship it, many do enjoy and admire their friendship. And since they are friends, this would make them fit the friends to lovers trope. Fans like to imagine that their relationship would involve mutual pining as well. On AO3, there aren't many works of the pairing, although there are some.

The ship became a little more popular when Day 24 of After School Hanako-Kun came out. Many assumed that the line about divorce implied that the two were once married.
