There is no confirmation, it s just suspicions that are confirmed every chapter, there is no other explanation to why eunhuyk turned that way , the Guy waited for her in every corner, protected her , listened to her ! And the way she s happy when she sees dohwa and she even blushed in the previous chapter. ( i dont think they d bring dohwa back just to be the second ml again)
I’m team dohwa & I 100% think Eunhuyk is going to be endgame. The fact that he was perfect beforehand & now he’s like tortured & hasn’t talked about why he left means that later down the storyline he will. The author is setting up tension right now between the two ML, but it’s obvious Eunhuyk is endgame.
(≧∀≦) i think everyone is seeing it from a different perspective, it depends which side you re on ! I am team Eunhuyk even though i adore dohwa but he doesnt deserve someone who picked him second cause it didnt work out with her first love, he s too precious i want him to be loved whole heartedly! I dont hate the new Eunhyuk but the old one deserves another chance / explanations, he was a kid too

I always suspected it , cause the fl wrote a whole novel for her favorite second ml , they ruined my Eunhuyk just so we could accept suae s chouce at the end .
He was so perfect , he exceeded all the ml in every manga / story i read , but they had to destroy him for the plot ! I ll never forgive them
