yeah I get what you're saying. Personally, I like the fact that we get to see how Jake's devoted actions and feelings towards Shin are solely defined by who he is now rather than any sad/traumatic/tragic past events that might have happened to him (I'm sorry if I haven't explained myself better ). It's like Aizen Sosuke from the anime BLEACH...his my greatest villain because he just exists as is without any sob story that we tend to see. I love their mysterious nature.

Jake is honestly one of the best well written characters. Even though we don’t know his past or what he went through but I love how his flaws never made him lay hands on his lover once (holy bare minimum ik)
