Could not have said it better myself!!!
As a woman, if someone that I was paying to do a good job had slacked off like that, I would've immediately fired her. Work is not a place to do as you please. But if her male boss did that, someone may have screamed sexist. But anyway that's to realistic. Manga speaking, I just hope she apologizes to Ruri, poor baby was crying so hard and felt so bad. （/TДT)/ I used to have a mild stuttering problem (so did my uncle except I think his was worse that Ruri's) But my mother talked to him and helped him fix it a lot and mine too. Now I only stutter when super excited and my brain is going to fast for my mouth. I hope Ruri can overcome his speech impediment. My sister overcame hers (she had a lisp & slur[still does but it rarely comes out]). I'd love the seme (fgt his name) to help him do it. But seriously though, she needs to apologize, she literally bullied him. Work is not the place to go off like that. At least give her some type of penalty. ヽ(`Д´)ﾉ
I do understand that the idea of the manga was to show that it is important to treat other people's feelings with respect but, honestly speaking, a woman like that should at least receive a serious written warning, pay cut, or even be fired. That kind of behaviour at a workplace is unaceptable.
Also, the tall guy didn't really do anything that he needed to apologise for. He wasn't obliged to accept her feelings. And he wasn't even offensive until she messed up with work and he called her attention as a coworker that had been hindered on his own assignement by her incompetence.
