This is the perfect Sangwoo reaction, tbh. It is a textbook reaction. Emotional abuse obviously stunts emotional growth, and for Sangwoo a lot of the stunting was centred around love. So, it makes perfect sense that he wouldn’t really be capable of processing something like this without either freaking out or getting angry. When people can’t understand something it makes them afraid. It makes them angry. It’s almost a reflex. Like someone who can’t take a compliment blushing in response to one. They just can’t process the words they’re being told. Bum has basically just told Sangwoo he will be with him forever. To a man who is so desperate not to be alone, but is so sure he will be, those words must be incomprehensible. 

Plus, he’s a jealous, paranoid son of a bitch.
