An incredibly adorable manga with more of a focus on comedy. There's not too much plot or depth but it more than makes up with it with it's humor and cute character interactions and even cuter character art. Strong blush game here. If you're worried it's more of a gag type manga then fear not, for the yuri aspects is 100% solid as well. The son's misinterpretation of his friends feelings adds a nice balance to the whole thing.
The 18 to 36 age gap is pretty large but they handle very well imo. I wouldn't consider that a reason to pass this up if that's a concern. At the end of the day it's just another romance manga that's idealistic and wholesome. No need to warp this into some grand question of morals.
