This is a total gem. There's age difference between MC and ML in most of the worlds and I find it so interesting and refreshing.

If you don't mind age difference, read it. It's really good.

Read up to the end of the first arc, c31

Tbh, kinda mediocre. The MC's character seems good, ML is okay but basically had no presence (and fell for MC way too fast). However, MC felt way too OP. Maybe it's given his academia background so the other arcs will have less of it, but it just felt so golden finger and made the story not that interesting. Face slapping was so direct, I do appreciate that the lines of morality are kinda blurred.

Idk, doesn't make me interested enough to continue.... more>> Might change if some of the future arcs interest me, but nothing really stands out to me from this story. I'll give it the benefit of the doubt and say 4 stars, but tbh arc one felt like 3 stars from quality. <<less

Amazing read! It’s very good, I like how MC adapted to his situation and even when he had kids he treated them fairly, we rarely see any transmigration into someone older with kids! It’s quite funny to see! I like the bond between the MC and ML, ML is adorable and quite thirsty for MC

1st Arc is so promising and world background almost perfect like what they research and about math theory, author seems like write that with heart, but arc 2 until the end it's just like.... deadline lol. Not bad, just like another QT, MC be too OP and every problem solve with previous skill they get, not a bad thing but just make it a bit boring. Face slapping ok and focusing on the plot, don't expect too much for love line bcs yah it's just fine. The end of story... more>> just :/

I think the Author just run out of idea.

Spoiler

MC have this skill like Chinese shaman (I'm so sorry I forget the name shaman in chinese) and the chapter after this arc using shaman skill the rest of arc so that's why it's a bit boring not like first arc.

And warning some r*pe (?) Scene, so basicaly MC get frame to drink aphrodisiac and ML end it up in MC room, ML reject original character to have s*x understandable but when MC replace OC, MC still forced ML to have s*x with him.

In some ARC MC not honest with his plan and don't seems have believe in ML

I think just first ARC really good.

Really like the first world, but not much the following world. Maybe because I MTLed it, but regardless, the first really hit the spot and also because most of the Bl QTs I read does not have that kind of theme. Aside from that, I like MC and ML its just that the theme is not my cup of tea. But still, if I have time, I would like to continue other arcs in case there will be a good arc that I'll like.
