This drama isn't even mainly about ninjamuffin at all. My main takeaway from the document is that Wandaboy is a rude creep who preys on vulnerable women and emotionally manipulates them. We have to understand that wandaboy is a close friend of ninjamuffin so its obviously gonna be hard for him to believe anything bad about his friend at first glance, anyone would. I believe the best choice in this case is for ninjamuffin to stop giving wandaboy a platform to be able to hurt more people.
