I don´t know how do you feel it, but I feel that the dialogues don't flow and that makes tiring to read all what they say

I know what you mean. Maybe it's the translation or the original is also like this.
And I kind of don't like the manga, because of this point and the plot is kind of avarage (if he ends up with sensei, then I may like it better, but I don't think it will happen).
Well I will just hop on to the next manga and try it there ╮( ̄▽ ̄)╭

Seriously, they just need to talk to each other face to face and catch up with what happened. ( ̄へ ̄)

A plot device for drama ╮( ̄▽ ̄)╭

They were kids. Siwon could have misread or mispronounced Jinha's name and have been calling him by the wrong first name all his life without realizing it. I have seen in several manga where someone misreads someone else's name, or they give them a nickname because they can't pronounce the real name (my best friend Krystal became Khistle because that's how her nieces and nephews pronounced her name when they were little)
What an awful mother. (⊙…⊙ )
