Chikasugiru Futari

Synopsis

From the moment they were born, they’ve been together through everything—waking hours, sleeping, and even bath time. At this point, calling them "childhood friends" feels a bit too soft. No, these two are "Sh**-tier Friends." More than childhood friends, but less than lovers. Having come full circle, they're basically an old married couple. The curtain rises on this "Sh**-tier Friend" rom-com, where the sense of personal space is completely broken! https://www.cmoa.jp/title/360696/
