Now that I am 21 years old, I can see all the problematic stuff this manga has (the fact that Aram IS STILL A KID, even though his appearance says otherwise), or all the misogyny that is showed from characters such as Jeile or Razalude (even though it's showed with "humoristic purposes"). But being aware of those aspects does not mean that I did not enjoy rereading it, nostalgia factor involved.
It is a good shoujo manga? Well, yes. The romance is showed beautifully, with an art that has a strong fairy-tale aesthetic. But, does it shows a healthy relationship? More or less. This is a manga from the 2000's, and healthy romance was not the norm back then.
So, would I recommend MeruPuri? Yes, if you keep in mind the toxic aspects, like the fact that Aram is a 7 year old kid that falls in love with a 17 year old teenager.
