I used screen translation so im not sure about my understanding; but basically the ml was crazily in love with his mentor, and since they broke up, ml would see the tattoo that he did on the mentors body on everyone he sleeps with (hence the ed). He also saw that tattoo on the mc body and tried to do that design on him ( not sure about this part). And then the mc found out, crying on both side and then happy ending
Like i know it makes sense (?) but at the same time i just want the mc to get the hell away and find someone else
