[Nautical]

Wow this translation is way different

I'm a little confused -- this would be Chapter 7.2 rather than 7.1.

We have both ch. 7 and 7.1 published previously.

"They are already break up" they said

The translation is so different from the other version, I had to look up the original Japanese and I'm pretty sure this version is inaccurate.
On the 5th page her little sister says, "でもお姉もそっちなのかあ…” ("But big sis you're like that too...") and she replies, "血かしら” ("Blood maybe"). Given the context, I think it's pretty obvious they're talking about sexual orientation and genetics, and not literal blood. There are also no mention of lips.
