ummm for me i feel like there’s a lot but one i remember a lot is the words in your snare second couple it was not fair they only got 2 side stories and just called it a day author should've explored it more hell it should gotten spin off like bad apple from red candy matter of fact in both those stories red candy and and twiys i didn’t like the main couples they were boring and dragged way too much so it was easy to be distracted by the other side characters

who do you wish got more screentime, better development, a whole spinoff...?
mine is the blink-and-you'll-miss-it hint of the relationship between the MC's sunbae/former crush and the ml's ex-lover in love for sale. still hoping they'll get their spin-off eventually! it didn't seem completely off the table for the creator...
someone asked this earlier and I would have replied but I seem to be blocked (not mad about it, but why?)
