Okay so basically the sister thinks they were in love and thought that yule didn't know how to confess his true feelings and just thought they had a little rut, so she tried to help things work out but after figuring out that yule did something worse than just harassing and actually turn to r*pe she decided to give up on the toxic relationship and let them go seperate ways. (Hope this helps) :p
But like what was the SISTERS deal
She’s the only one I couldn’t really understand like can someone explain her goal
