He really didn't want to make this hard for her but he had to pretend to be angry and heartbroken so he wouldn't seem different from others according to zero.
"No no! I swear I really love you,it was all real,I was always honest. Everything I did, everything I said,they were all true,I meant them all, please believe me." She cried even harder,still on her knees and desperately trying to explain. She wanted to make Alex understand that she wasn't acting all the time they had been together. Well,she probably would bite Alex if she knew the guy was just playing hard to get because of his system.
Alex was pained seeing Becky's miserable state, but his face didn't show it. His thousand years old will seem to be failing him; he just couldn't look at her continue in self blame anymore. He knew she was also hurting and did not have to go through such a situation. Harrison! Yes,he would be the one to shoulder all this; Alex vowed to let out his grievance on him when he gets the chance.
