well male lead seems to have been betrayed by his lover so yeah trust is what he cant do right now and the way she is acting it was logical , i mean your girlfriend just met another man and hid it from you first thing you will think is 'it is the end for us ' and will start to distance yourself because it is natural no matter how later it is revealed that it was suprise for party or gift that trust wont be back , and that gift wont sustain the pain he felt and maybe after so yeah in realtionship number on priority is communication no misunderstanding crap if you think its not working it better to end and see of each other on friendly terms then drag a toxic one . I hope female lead learns this i mean just reverse the situataion with male lead hiding it from female lead she will cry and ask for shoulder and sympathy but when , female lead does it society say that he must have not loved her or hit her or he was cheating . What is ntr sex with a person other than your lover then what would you call this if you hid something from your most important person image the pain he/she will feel . I feel bad for male lead betrayed and betrayed and again and again its better to close the heart then repair after betryal for betryal again just adopt someone make him/her a better person you dont need sex to live you can always go to brothels , just give my man some happines not pain .
