I appreciate that there is some plot development in this chapter along with the required physical engagement. Still believe he’ll be the replacement they need. Thanks for the translation.

[AnacondaHL]

I boi, plot with my plot.

When Natsuki says she'll do something, she will

Natsuki always finishes the job . I do wonder how they became friends given their uhh... Mathematical quirks lol.

Natsuki shall summon the power of horny!

Honestly, kind of jealous.

You got a girl who loves you, and who you love, with you at almost all times of day. The sex is good of course, but it's nice to have that special someone who you can talk about anything with no matter how mundane or weird it is.

It better be where he sneakily screws them both during the performance. That would be exciting AND it'll hit quota.

 

[nueee]
