Either its just a quick fap, or a part of setting that highlights the difference in moral norms between dragons and other species. Hope its the latter
I get that, but then later [spoiler] Valos says that he's had feelings for MC since they met basically, and if anything it was just a personal opinion that regardless of whether or not it's the social norm for them I personally wasn't gonna fall head over heels for him if he couldn't try to express those feelings for me first over the other dragon he's found[/spoiler]. I'm not ragging on the game or anything, I quite like the characters and world building, I was just noting the one actual complaint I did have about it so far
