Who it's for, and whether it holds up.
Quick transmigration stories live or die on their arcs, and this one has a narrower brief than most: every world, the MC coaxes the blackened villain back from the edge. He used to be a system before becoming human, which means he still likes being petted and treats affection as a kind of mission parameter. It sounds absurd and mostly plays that way, in a good sense.
The early arcs earn their charm. The MC is proactive, genuinely devoted, and disarmingly sincere about wanting to heal the ML's trauma. That consistency is the point of the whole thing, and if you're reading this genre you probably already know whether you want it. The settings range across ancient China, a zombie apocalypse, and an interstellar future, so at least the wallpaper changes.
The problems are structural. The formula is exactly what the title says, repeated with limited variation. By the middle stretch, the ML's darkness tends to resolve a little too smoothly, and the balance tips heavily toward kissing scenes at the expense of whatever world the current arc is set in. Some readers find the MC charmingly naive; others find him exasperating, and his dimwit system companion doesn't compensate. Later arcs also include significantly darker material, including slavery and torture in at least one arc, which lands hard against the otherwise fluffy tone.
At 4.1, this sits firmly in the "good for what it is" tier. If a relentlessly devoted MC healing a yandere ML across multiple worlds is exactly your thing, it delivers that with consistency. If you want arcs with real plot weight alongside the romance, the engine here isn't built for that.
