A Couple Who Got Married First

Dojun, who married out of necessity and immediately left for a foreign country, suddenly appeared at his marital home and then at his company, without any prior notice. He brought with him several photographs. 'With this innocent face, was she always seducing men?' 'I thought we had only two months left until the divorce...!' Is this marriage really okay? And who could have sent those photos to Dojun?
