Both are saucy in their own right, though I argue "Love in the Air" is saucier. Also "Love in the Air" involves 2 couples, as opposed to "Bed Friend" only focusing on 1. So you get double the sauce!
Okay hear me out. Do I think "Eighth Sense" is better than "Our Dating Sim"? Yes. However, if you want a more condensed love story thats also very solid watch "Our Dating Sim". It's very sweet and also set within Korea.
Both are set in japan and both have wholesome layers to them. However, (arguably) "Cherry Magic" is better at its storytelling and its main characters are more well fleshed out.
