I stand with this comment. People are way too immature nowadays that they things solutions happen overnight. The author wants to show that when you want to fix something, it takes time. It'll look wrong and weird, it might not feel like the fixing process is happening at all, but after quite some time, you'll learn how to do it properly.
Sadly nowadays people want everything to happen overnight and it's so sad how immature people are, even the older generations.
But that's just my opinion because from the way I grew up, I started maturing at the age of 4

Nah, it's exactly like you said. That's why I started asking what they want the author to do? What kind of apology do they need for Jiho to be forgiven? Or they want Jiho and Inwoo to part ways forever? They say Inwoo deserves better, but can Inwoo truly survives without anyone's love? Can someone in this manhwa handles Inwoo better than the current Jiho does at the moment? I was wondering if they have an answer, instead of complaining without havibg any better solution.

Oh trust me all they wanna do is complain.. there are multiple things people want:
1- for inwoo to break up with jiho but then both will get depressed and the readers will be like "he did this to himself, they could've communicated with eachother rather than breaking up"
2- jiho could say he want a break from the relationship but then the readers will be like "a break from a relationship is an excuse to cheat on someone"
3- I don't even know maybe they want inwoo to kill himself or smth... people are so messed up in the mind from the immaturity

Well in the first place, cheating is a "choice" and not an "accident". And Jiho chose not to in the end. He is having a double thought because he is not right in mind at that moment. He is having a hard time. But in the end he still chose not to. Nothing that fucked up about it. Unless he is already all naked and ready to get fucked, nothing is really fucked. What he did to apologize is enough to show where his real emotions and feelings lays at. The characters in this manhwa are not perfect. They all have flaws but that's fine, that's why this manhwa felt so real and good to me and all readers that agrees with me.
God, it was apparent that you guys either never be in a long lasting relationship, or probably never been in one at all.
What more could you be asking for Jiho to do? Reminder, I hated what he did too, but here he is, quitting the job that he loves to make up what he has done to Inwoo. Read the comments saying "oh all he needs to do is to quit his job to make up, that's it?" That's such a shallow take on the whole situation.
You don't understand that it takes a lot of dedication to quit the job that YOU love, that you have been building by your own hardwork (like what Jiho did). But he did it anyway to have a lot of time to show how much he loves and cares for Inwoo, he showed Inwoo in ACTION, that he is important enough for him to quit his job for, and he'd love to spend his whole day, whole week, whole month with him.
He wakes him up early to get breakfast, making sure he ate at least twice a day, on the way to thrice. Taking him out to get fresh air, showing him how much he and people loves his work, staying by his side from morning until the next morning. Showering him with love words, praises, hugs, kisses, making sure Inwoo knows he loves him and that he is not alone, to get him out of his depression and loneliness state.
And you guys still cannot forgive him. That's why at the beginning I said "it was apparent that you guys either never be in a long lasting relationship, or probably never been in one at all." Because long lasting relationship will definitely comes with apology and forgiveness, they made mistake and hurt one another unconsciously, but they still wanted to make it work because they love each other, how? By apologizing, forgiving, and showing how they change for the sake of their love.
It's not like Jiho did something unforgiveable like cheating. Tell me, exactly what else do you want Jiho to do? To grovel by Inwoo's feet, apologizing in tears and thousands of words? Or what?
