none of the kissing/smex happened in the novel. and the ml admitted that what he felt for ujo hyung wasn't something romantic. he just felt grateful and wanted to repay his kindness. and it is such a huge contrast to the adaptation. in the novel it was all in the mc's head (that the ml loved ujoo hyung that way) and was all like "well, there is nothing i can do abt it. best i could do is ease his pain"
the changes are not necessary. us, bl readers, aren't smut hungry as they make us. i personally think that the original novel had more depth and the feelings of frustration made more sense.
