"Elle calls me daddy too"

A splendid confession! Now quickly, accept her confession in russian!

I think "sneak attack" should be translated as "guerrilla tactics" instead. Since wars of attrition basically means "winning through making the enemy unable to continue the war" rather than through conquest or annihilation. Harassing supply chains is typically a key strategy in attrition warfare.
The other points are valid.

The queen is using "punishment" as an excuse to let Elle leave, which is why she set Elle up for failure. To what end isn't explained yet, but you can kind of call it a necessary evil. Since the fairy queen wouldn't be able to send Elle out under normal circumstances she had to manufacture an excuse.

Called it

At this point I think you could depose him honestly.

I 100% imagine Mo Na Ye making it himself.

I love how absolutely cartoony it got in the middle there.

Boy gets absolutely destroyed XD

Have you read Solo farming in the dungeon? Cause if you haven't you're missing out.

Its kind of a shame. I wanted Sasha saved for last.

This starts out as mindbreak level fucked up and then gets cuter as time passes but honestly my anxiety that there'll be a relapse is so fricken high.

That meme at the end is slander! Sou would never betray his cute little sister like that!

"Those who can't bend often break."
I personally think she's strong enough to overcome this though.

Not yet. Though they did it in a way that doesn't annoy me like most of those indecisive mc stories. In this one they make the girls interesting and the MC isn't a complete beta so its fun to read.
This is just the finale of a mini-arc not the story finale, though.

Or maybe it was a set up to give her an excuse to send Elle to the dungeon farmland?

I think he was leaving them there to keep them safe... hopefully.

Taking his sister to a brothel lol

The rescue party looking for his mother needs help and the letter is already six months old. Anything could have happened by now.

Is that really the image you meant to post?
