The boundary of delusion

Thank you !!lヾ(☆▽☆)

What’s your fave amongst all of them ?

Ooooh, if I had to pick a top five with the most angst amongst them and rank (based on my preference), it would be the following:
1. I'm not your guide to destiny
2. Passion RAGA
3. Love jinx
4. Protect your purity
5. When pear blossoms bloom
(NOTE: Love jinx includes a red flag - I'm very biased, I love him (don't judge me please, I am weak to devoted red/black flags and I already judge myself just with that enough), so just be aware if that's not your thing. ALSO, in I'm not your guide to destiny, PLEASE don't read episode 33 and the first 18 pages of episode 34, the illustrator took creative license on things that weren't in the novel and were COMPLETELY unnecesary. Other than that, it really is a great story)

These don't have a lot of angst, but peak recommendations nonetheless, or to be called "My Honorary mentions" (in no particular order):
