Agree..i love the uke..don't get why people call him annoying..
Probably because Subaru comes across as opportunistic. But really, he has already sized this sensei up as a gormless prick who coasts on the goodwill his father generates and treats everyone with the same casual contempt. He needs somebody smarter than him to teach him a sharp lesson. Subaru tried to appeal to his compassion, but he kept underestimating the kid and played with him instead. Serves him right.
Not that I don't doubt he and Subaru will end up as a couple in the end, but it will either be a very good and unpredictable story where he learns and grows into a better human being, or it will be a sloppy romance where his considerable dumbass flaws get swept under the carpet. I hope it's the former.
That uke is the best one ever! That'll teach Sensei to stop riding high horses, to keep his trousers zipped and his ego deflated to normal size. I love that kid.
