a small disclaimer, it’s been 3 years I started writing Feel the heartbeat, and so there are many small inconsistencies and mistakes.
For a few to mention, for the initial plot, I made Soobin the older person (bcz he was also older in one of my other books and it was easy for to visualize).
Yeonjun and Yeji were supposed to be engaged, but now that the plot I have is changed, they are supposed to be married and I have changed in the appropriate places.
Last, the timeline, now that I am thinking of it, Ryujin and Soobin are 5 years married, and so for that sake, don’t compare them with the age of them in real life. You can imagine as you wish, but I would just think they are all in their late twenties.
