I have a whole bunch of DL Site recommendations. You're after yandere men right? I'm listing them by how hard-core they are (most to kinda least, but definitely not vanilla). Yes, I have a problem, and yes I practically bought all yandere stuff from DL site
• I'm Confined and Sexually Trained by My Obsessive Yandere Brother
(Note: this is the most similar in tone to this manga, but tw for incest)
• Rin's Dark Room ~everyone who ever bullied me is now dead
• Deflowered ~My Possessed Childhood Friend Wants to Come Inside Me~
• My Old OSHI Became Truly, Madly, and Deeply Obsessed With Me
• Cannot Escape From My Yandere Colleague's Mad Love
• Invigorating Extrovert Colleague Has Already Trained My Body??
• Dependency Prone Obsessively Loving Guy ~Your sense of reasoning is ruined by Ryou Shinonome~
• The Ex-Saintess is Imprisoned by the Hero's Obsession
• How To Love A Crying Monster
• Caged in the Rhythm of Rain ~my boss, who I adored, was actually my stalker~

• The Virgin Incubus Cannot Resist ~until he corrupts his foster witch~

Also I found these on this website:
• Otome Game 'Kuro†Dora -Kuroi Seijo to Ashiki Ryuu-' ni Isekai Tensei Shitakedo Murigeu, Tsunda.
• My Cute, Naughty Rin: Surrendering to Her Obsessed Trainee Next Door
• My Childhood Friend Loves Me Under Hypnosis
• The Night I Drowned in His Obsession: The Devoted Ex I Shattered
• Tonari no Seki no Hen na Senpai
• Sukui Sukuware (not very smutty)
I have a lot more. Maybe I should actually make my own list lol. I only really like yandere or very possessive types, so some of the yandere list on this website aren't yandere enough for me haha.
heyyy it seems like you read a lot!! do you happen to know a smut josei where the ml is a knight but hes always shy around his wife until one day he got caught by a spell that made him being his trueself. hes like a big scary teddy bear but is gentle to his wife!..since bato has gone (rip all my list), i couldnt find it anymore since i dont remember the title… if you happen to know, do tell me in the comments :D

anybody who can recommend another one like this pls all the new ones ive read are kind of passive when it comes to the genre (/TДT)/
