I feel like they're a bit similar to Kim Dokja and Yoo Jonghyuk from Orv, except the fact that this is a historical isekai and Sei san isn't a self sacrificial squid that Kim Dokja is. And Aresh doesn't choke seichirou, unlike how Yoo Jonghyuk choke hold Kim Dokja on that bridge.
why does the long haired dude look sm like Geto???
