I think the doc wasn't serious at all...he was just playing around...but since dojun just straightforwardly asked him .the doc couldn't refuse so dojun don't get hurt...atleast the doc did one thing right...if he had just told dojun the truth...i would have been so mad
It doesn't seem right....is the seme planning some sort of revenge or what...i don't know ( ̄へ ̄)
