In chapter 32 I did not understand why Gyeol made a shock face when he entered Doyoon's room and saw a stack of books piled on the floor, chapter 39 explains it, the same books are stacked in old Doyoon's place, on the floor at that, and the freaking details gives me goosebumps! What a story and I so love it!!!
Story could have been better if she already fessed up 10 chapters in
