Hi! I am looking for a novel I read a long time ago and which I never finished. I only remember the first arc a bit: MC is a supportive male character for the FL. At the beginning of the novel he came back from abroad for her wedding as a friend. FL's brother (our ML) is secretly in love with MC, he is crazily jealous of MC towards his sister. I remember he kidnapped MC and hid him on his private island for a while. That's, basically, all I remember. I am not sure if I liked this novel or not, I don't remember why I dropped it, so I want to look it up again. Thanks for any help in advance.
