Isekai Chan!

Your family vanishes without warning, leaving you the sole caretaker of the apartment building they used to run. Then a handful of girls from another world land in your life with nowhere else to go, and you're the one who has to sort it out.

You take them in and promise two things: help them find a way home, and help yourself figure out what happened to your family. To keep everyone fed and the debts paid, you reopen the ground-floor café, which becomes the daily grind holding the whole arrangement together while the girls slowly adjust to a world that isn't theirs.

Day to day you're running the café, working through story chapters, and managing a household that keeps growing stranger. There's a fishing minigame, a combat minigame, and some late-night mischief around the building that has its own dedicated events. It plays like a sandbox with a schedule to keep and people depending on you, rather than a straight visual novel.
