Do we spend a lot of time in the flashback? He's just so awful, and I know it gets worse. I'm thinking of waiting....
[lowkey spoiler for other people] The principal story spends some time in the first timeline from Sejin's point of view, after that we go back to the present timeline and then a chunk of the extra stories revisit the first timeline but from Ido's point of view. In my opinion is not a hella lot of time but keep in mind that I read the whole thing in a couple of nights and the rythm of a book (with the complete story on top of that) is going to be different than reading while waiting for a single chapter every few days, so... Maaaaybe It would better for you to let it marinate and wait for the manhwa adaptation to be complete (〜￣△￣)〜
Televisa presenta: “Los ricos también lloran”
No te quiero mentir
No esperaba tu amor
Porque tú no sabías amaaaaaaar
After reading the novel (although with auto translation) I have to say that what kind of comforts me a little is that at least (the bar is in hell since this is supposed to be a redemption story with romance involved) Kwon Ido actually SUFFERS and UGLY CRIES and we are all going to enjoy his tears, like, this man is going to repent and cry more than Verónica Castro in old telenovelas for Sejin's forgiveness even of his initial plan after saving Sejin's Life could have ruined everything (and Sejin tells him after learning about it, he is an angel and deserves better ( T﹏T ) )
