I Pulled an All-Nighter in an Internet Cafe, and Three Beauties Won't Leave Me Alone

[Urban Fantasy + System + Daily Life + Feel-Good Story + Multiple Heroines + Light Suspense + Twists + Romantic Tension]

I was just gaming all night in a private room at an internet cafe. I never expected someone to push open the door at three in the morning.

Three beautiful women, each with a different personality and bizarre behavior, suddenly barged in and took me for the only person they could rely on.

Before I could figure out what was going on, a notification popped up on my phone:

[The Ultimate Harem System has been bound: You are now responsible for them.]

From then on, I was forced into a cohabitation routine I couldn't escape.

Keeping their emotions stable, solving problems, handling love-triangle disasters...

And with every time I was made to "take responsibility," my life spun further and further out of control.
