Upon arrival, we were greeted by Shinseki's child. During our conversation, it was mentioned that "shinseki no ko to o tomari da kara eng free," which we interpreted as an indication that because we had stopped by to see Shinseki's child, a particular service or item was offered for free.

A probable intended meaning: “Because I’m staying overnight with a relative’s child – English free” — perhaps requesting an English translation, or indicating that the content is an English-free (Japanese-only) explanation of sleeping over with a younger relative.

The title roughly translates to "Staying Over with a Relative's Child," or in some circles, "My Relative's Daughter Is Staying Over."

In Japan, the concept of (お泊まり) typically refers to a sleepover — often among friends or cousins. However, when the phrase specifies shinseki no ko (a relative’s child), it implies a slightly different dynamic. Unlike a casual friend’s sleepover, an overnight stay with a younger relative carries a sense of duty, care, and familial obligation.

Shinseki no Ko to O Tomari da kara (roughly translated as "Because I’m Staying with my Relative's Child") is a slice-of-life adult visual novel known for its "comfort" atmosphere and simple gameplay loops.
