Dad: hi you're both sisters omg I'm sorry runs

Perfect, I love it

I kind of wish there was a manga that did something like this every arc, like one arc they would be able to read minds which then resolves itself, then another they swap bodies, one day a girl becomes too big/small, one grows cat ears, one becomes a vampire girl then later on it all jumbles together and then SURPRISE YOURE SISTERS

All with no explanation on why it's happening

Preety sure that's Kokoro Connect in a nutshell lmao

Difference is that Kokoro is a drama and not a comedy

What other tropes/cliches/premises does it need?

It's not made obvious, but there are at least three more premises hidden on the first page: Ryou is a high school girl (School life), Yuna may be an Office lady, which would give us Age gap for free.

More premises that are missing:

• Ryou's family turns out be rich (Ojou-sama) and Yuna starts moonlighting as her Maid.
• Ryou "accidentally" books Yuna on a lesbian prostitute service (Pay for gay).
• Flashback of when Yuna was a Gyaru in high-school, while Ryou led a Delinquent gang.
• Ryou is actually an Assassin sent to kill Yuna, and vice versa.

What else did I miss?

(Based on a game)

Hahahahahaah

I only realised the title at the end of the manga. 10/10
