I thought so too it made it so refreshing but it also made realize something a lot of japanese erotic content usually borderlines on rape or basically it seems for them it's considered more "arousing" when the receiving party shows some type resistance or embarrassment even for those who watch hentai there's always gang rapes, normal rapes or blackmailed rape it's pretty awful but maybe that's less of big deal for them I guess, idk I'm not japanese
It was sooooo refreshing to see the uke from the main story actually express his pleasure without acting ashamed or embarrassed. (⌒▽⌒)
