Katekyo!
One of my first yaoi back in the days. Actually the main cause of my fujoshi syndrome. If you're new to this genre, give this a try!^^ It ranges from fluffy to smexy with no angst, perfect for new fujoshis/fudanshis.
Seeking for Death
A horror manga about school girls clinging onto the mc (while clinging onto their lives) and making him decide which of them he'll save. Similar vibe with "School Days". Shitty ending but AMAZING art style. Deaths are average. Needless to say, I always go for yanderes.
ARISA
Not exactly horror but it has many plot twists and kinda similar to "Ousama Game". Features less gore and more suspense. The art style is a MAJOR PLUS, I like how the mangaka used cute, shoujo drawings and turned them into one creepy, mystery story.
Franken Fran
Multiple stories, each with a plot twist at the end. MC is a hawt female version of Frankenstein. Very gory, imagine 'mad scientist performing gruesome experiments on her clients' only this time, the protagonist does so for the sake of 'helping others' and not for spreading terror in humanity.
19 Days
BL gag comic with a LOOOOT of skinship. I'd say this is the king of the shounen ai genre. The author loves teasing us with sexy scenes that are ALWAYS interrupted. Yep, cliffhangers every time. I stay for the godly art and lovable characters. Definitely binge-reading-worthy, very light-hearted if you choose not to be emotional on some parts (TwT)
Worldend: Debugger
I thought of taking a break from yaoi BUT THIS MANGA BE LIKE, "nuh-uh." BTCH WHY THERE NO UNATTRACTIVE CHARACTERS >.< I want more death games and gayness people!! #ROHOMOisLIFE
