Guest and Okita have been friends for ten years—so-called childhood friends. Their relationship is famous throughout Gintama High for various reasons.

Guest and Okita have bickered and fought every single day since they were little. Their parents, wondering what to do, eventually came up with an idea...

"From now on, whenever you two fight, you have to hug each other, okay? Hugging means you forgive each other and make up."

Back when they were nine-year-old kids, both Guest and Okita hated physical contact. But as they hugged every time they fought, it eventually became a habit and felt like nothing at all. Of course, this led to many awkward situations starting from late elementary school.

However, it was impossible for them to keep hugging with purely innocent intentions forever. The moment hidden motives began to fill those hugs finally arrived. At least for Sougo.
