This anime is indeed great to watch.
First of all, the quality of the skin is really good, smooth and soft to the touch without losing elasticity. Many people think that good skin requires good maintenance, like otaku girls who stay up all day and night, disturbing their meal routines—their skin quality must be horrible.
In fact, the best maintenance is being young, plus having undergone Marrow Cleansing, solidifying body metabolism to perfect standards. Even without skincare, outperforming the actively-maintained rich ladies around the world—just look at Zhang Huaide, who even cured his myopia after entering the Marrow Cleansing Stage, oddly enough wearing a pair of plain glasses.
Next, the reactions are also very cute. Won't let you touch the top, won't let you touch the bottom, start wriggling when touched on the sides of the waist, only allowing touch on the central part of the belly, but not under the clothing, otherwise, they get angry.
