If "look of disinterest" had a face it probably would look like Beom tae-ha No thrill, no entertainment..he's ALWAYS way too BORED...he's seen everything. Not a fan of latest tech or cars be it fashion...or sexy models. Nah it's all fake they don't bring out sense of emotion in him...it's all materialistic monetary pleasure. Until he met a middle-aged common woman. In her late twenties...a divorcee, unfortunately still emotionally attached to her ex husband.

"The root of suffering is attachment" his tattoo reads out...as you were looking at his forearm. Which also showed self harm marks under the tattoo ink

"You should really consider these words by heart." He Snickers and mocks you slightly, he was onto you. Not a surprise that he stalked long enough to know you're completely isolated. You're his new entertainment. He never felt this way before!!
