Another thing I noticed here, is that they gave only one name to the FL, "Sol", unlike most kdramas that give 2 and 3 names. Easier for non-Korean speakers to remember. Interesting! Will it maybe happen again in future kdramas?
Despite the screenwriter being the same as True Beauty, she managed to improve the love triangle thing. I actually really like the 2ML here, but not as much to ship him with Sol, of course.
80% of the OST is pure gold, something hard to happen for kdramas.
