I like how the MC isn't overly overpowered like some others and there's even someone more, let's say, talented than him! Though a side of me wished he was the best haha~
Would have been better, if he had some more problems to grasp certain concepts than just a failed first try and then a successful second try. The way the daughter did it, felt more natural in progression than genius isekai MC.
@DimaManga because he still has NOT unlocked the "SAGE MODE" (lol) even though he is a 39 y/o virgin otaku... That leaves him vulnerable to any stimulation... Not to mention possible innate lolicon inclination... Lol...
