if there is not any specific genre then you can try " My Beloved Oppressor " "Wish You Were dead" "Pandora's Heart" "Usomeno Yado"
Olgami
Damn...OK.. you asked.
The first one is the hardest read (but great story) and the fifth is also angst but not that intense.
1)The Heroine Has Despaired / Heroine wa zetsubou shimashita
2)Averted Gaze R / Broken Gaze R
3)I Shall Kill that Sweet Devil /
I Will Twist the Neck of a Friendly Little Bastard / I'm Going to Twist His Neck
4)JK Haru is a Sex Worker in Another World
5)Return From Death: I Kicked the Bucket and Now I'm Back at Square One With a Boyfriend Who Doesn't Remember Me
Refer to the numbers as...levels.
BTW they are all enjoyable stories.
