From my experience with manhwas like these, i am expecting the inevitable chapter where we'll get a pseudo-NTR moment where Woojin will do it with the Sunbae and the classic open door moment happens wherein Wooyeon will see it and then sht happens and then yeah sht happens
no it will not happen like that because main character is woojin and wooyeon .so woojin will suffer but sunbae will not get the chance with wooyeon ,it's better if sunbae is the one that save wooyeon but i don't think author will make it like that
