Surprisingly no. Those 2 depicted are just side characters and actually have a somewhat healthy relationship. And the main cast is generally not that sexualized.

Not really. Guy in the bottom picture is a minor character. The show largely centers around a dragon girl (not the one pictured) who arrives at the human world injured, gets saved by another girl who works as a programmer, and then moves in as her maid out of gratitude. Dragon girl falls in love with programmer girl due to the kindness she shows her.

Not entirely, that artist is also a confirmed pedo
