I feel like LonaRPG has everything to create a truly interesting and terrifying yandere character
Lona saves someone like that noble girl on the way to Doom Fortress or recruits a companion and depending on the choices made they become more obsessive and abduct her
Lona is forced to be a good wife and do chores. constantly confess their love, "satisfy" their new wife or husband and if Lona fails she get disciplined for her own good
Lona gets well fed however the food is made with hair (and other bodily waste if certain fetishes are turned on)
If Lona tries to escape she gets her legs beat so she can't try to run again away any time soon
If Lona escapes without killing the yandere there's a chance of them randomly showing up in the open world (imagine waking up in the woods and hearing LLLOOOONNNAAAA~~ and them rushing at Lona full speed to recapture her)
If the yandere character is female she can forcefully whore Lona out or have a servant screw her so she can raise Lona's baby
It's also fitting that the only person that loves Lona (besides BoBo and Fat Bray) is an obsessive stalker
The yandere characters gender doesn't matter male, female (with a strap-on from snowflake since I know the developer thinks lesbians are cringe), femboy, futa
I largely ask since there aren't any yandere games that make yandere characters actually scary and hopefully this post doesn't sound I'm demanding anything
