i have a feeling that between being trash to hyojin (assuming it is common knowledge) who is an 'ex' on good terms (used loosely since it's all very cute and when they were teenagers) and being friends with amy who is the cousin he wants to push down an elevator shaft most the time, jinhwan might not be too keen on gunwoo and will probably ask sori an umpteenth amount of times how she lives with him since they're friends from daejeon.
