Sigh... work isn't going well. I might be laid off by the end of the year. I've started a Patreon, but all my work will still be shared for free, with simultaneous updates on both platforms. The Patreon is mainly for voting on new work ideas and accepting support.
Yamada Asaemon Sagiri in the original manga is a young woman (or young wife) with a widow-like aura, much like Soyo Nagasaki from MyGO. She's practically the perfect embodiment of an NTR archetype.
By the way, I'd like to recommend my friend's low-magic Roman historical novel, 《Martyrs of the Eternal City and the Millennium Oath》. It spans from 59 BC to 1453 AD. It's well-researched, slow-burning, and features a natural character growth curve.
