I'm not sure if it's the experience of reading a lot of manga, but I had the feeling since the first chapter that Seki was going to be the uke and Iwashiro the seme. It was in the small details of how they behaved from the beginning.
Same here. I’ve had this tagged as ‘delinquent uke’ since the beginning. I love when a couple has similar builds, though. It usually gives me a sliver of hope that they might switch, lol. But in this case, not so much. Seki is clearly going to be a cute and sexy uke.
I really want a story from the brother. I predict angsty.
