Oh crap. Thank you, I'm new in this manhwa ヾ(☆▽☆)
Basically, it's Hen beying torn between Alek (whom took a liking to him, prob bc of the mark) and Ivan (who marked him to begin with). It's implied Hen has been doing sexual acts with both of them, being unable to refuse either, and so he becomes exausted - and confused about his feelings.
Yeah, she was really nice<3 However the thing I didn't understand is how he suddenly showed up at Ivan's bed!!!
It's a time lapse! They are showing how Hen's routine changed, and that, as the days go by, he's torn between spending time with Alek and then spending time with Ivan. He kinda gave up on fighting his instincts, and is just now going with the flow when it comes to sex.
Can someone explain what happened in this chapter? http://www.mangago.zone/read-manga/the_devil_s_temptation/uu/the_devil_s_temptation-chapter-13/1/
SPOILERS:
Like how did he end up with Ivan? Did he fantasize about it? It actually happened? Hen went after him?
