the main couple was incredibly boring

idk if it was the script but i felt like the main couple was so boring. they literally had no personalities whatsoever, like the dude’s personality was just being a fckboy and liking butterflies?i managed to finish the show only for the side couples, they were soo much more interesting. it’s a shame bc han so hee and song kang are amazing and i felt the couple was wasted on this show?. i liked the point of the plot tho because it was really realistic and people actually go through that stuff
