You mean you jumped from 20 to 50. 30 chapters and you did not miss anything? then 20 chapters from 70 to 93, and another 10 from 93 to 103. I mean is this story really that bad that you can jump like this and not miss anything important?
I read it from 1-20 then jump to 30 then to 70 to 93 to 103 up until the last chapter. It's not that bad but the situation is repetitive. There's supposed to be a suspenseful revenge but you'll get it along the way. The seme didn't also get an arc until 103. The jealousy is unbearable because he also treats uke badly. So yeah... but give it a shot you might like it.
This reminded me how I skipped filler episodes while watching naruto shippuden
This is how I read it... 20 jump to 50 junp to 70 jump to 93 jump to 103. I didn't miss anything.
