My Sister Is Prone to Depression? Then I'll Have to Be Firm with Her

[Multiple Yandere Heroines] [Powerful Figures with a Surprising Side] [Love Rivalry] [Turning the Tables]

In his previous life, Lin Feng worried himself sick, constantly on edge and afraid that his four severely depressed adoptive younger sisters would slit their wrists or jump off a building.

Only in the moment before his death did he discover the shocking truth.

His sisters, who seemed like they could be blown over by the wind, were actually freaking financial tyrants, martial arts fiends, and the top assassins of the dark web!

Their so-called depression and threats of suicide were all an act to make him worry about them, so they could claim him as their own with a clear conscience!

Now he's reborn, and has awakened the Yandere Rescue System.

From the start, his youngest sister once again fixes him with red eyes and presses a fruit knife to her neck. "Big brother, if you can't explain what our relationship is, I'll die right in front of you!"

The System warns: [Expose them on the spot and they'll break both your legs and lock you in the basement. Take charge and discipline them to earn massive rewards.]

Since you top-tier powerhouses insist on pretending to be depressed girls,

then don't blame your big brother for showing no mercy.

I hear you want to kill yourselves every day?

Then line up nicely and wait for your "one-on-one intensive treatment"...
