Killing stalking doesn't have rape (yet) but you may think it's dubcon (I don't think so). Warehouse is full of rape but we don't know the reason yet)

if you haven't already read these i recomend them, it's all the gay webtoons i can think of:
19 Days
Never Understand (out of control),
A Man Like You,
Window Beyond Window,
The Baker on the First Floor,
Blood Bank,
What Lies at the End,
Royal Servant,
All About Lust,
Heaven & Hell Roman Company,
Delivery Boy Debacle,
Thank you for the Meal,
Lover Boy,
Alice in Adultland,
Back in Time to You,
(these ones have a darker theme to them)
Killing Stalking,
Dark Heaven,
Warehouse

Spring in the Heart, I highly recommend you try. It just came out, and it isn't on mangago, but you can read the chapters available for free on Lezhin. It's very beautifully drawn, and it's hanahaki, which is something I haven't seen yet in manga nor manhwa, so I'm especially excited. I really like it! ٩(๑❛ᴗ❛๑)۶
I just finished reading Raising a bat and it was so awesome that I'm now obsessed with it. I'm interested in reading other webtoons or manwha with a gay romance as there's a nice and different feel to them compared to yaoi. I'm open to anything as long as there's no senseless rape (i.e no "I raped u because i love u", but if one of the characters has trauma because he's been abused in the past and it's handed seriously then it's totally fine).
