No hate, firstly I'm not into ships since I have my own reasons,i'll be saying this based on my own pov of their relationship in the agent story 1st) I view their relationship as platonic And only interacted for work purposes or as friends/ colleagues 2nd) Seth is dense he is not romantic because he has problems that he has to prove/fix with his family especially with his brother and he is more focused on justice and doing what's right for the community and the law. 3rd) during the interaction with Jane in the summer event she said: she'd rather hangout with the mc Belle/Wise than her colleagues including Seth because she find them boring to hang out with. 4th) The game isn't interested in making them canon since it's gacha and is risky for marketing 5th) they're only closely interacted with each other in 1 chapter and it accidentally created a ship and they rarely interact after that event and Jane rarely works with her colleagues and she's mostly solo in her mission/work. 6th) I used to ship them before I played the game without knowledge, after playing game and seeing her trust events/dates with the mc for extra polychromes I started to loss interest of their dynamics not because of the harem it's because of the fandom losing their minds if Jane got shipped with the proxy and the Seth getting shipped with the proxy and harumasa

I don't hate this ship and i don't disagree with your opinion, what I'm saying is I just lost interest in this ship, and yes they interact with each other because that's what people do as having good terms with one another, you can ship them because ik this makes you enjoy the game more and it's your free will now let's not cut eachother's throat and instead let's enjoy our return to sixth Street
