May I ask why the other tenant was mad that the man and her landlady were going out? I felt like I missed something
I got a bit confused about it, too. I don't remember what episode it was, where the guy jokingly or straightly asked her about it but she just laughed.
On this drama I learned how pathetic human life really is. That we need to deal each consequences and problems base on what solutions or actions we did. P. S. I really hated the shitty husband.
She just keeps on being nice to the other guy even tho she already knew that he is from the rival company. Thus, giving her future problems that all came from her stubborn actions and thinking.
