Even if the car accident didn't happen they would eventually be back together. As you can see in ch93, haesoo is telling taku he's not sure he can't let that happen (cut out joowon from his life) that indeed he don't want that to happen, and that he has something to tell him (obviously to tell him the one month free trial is over) and taku knows it and interrupted him. Haesoo was going to finish what they had with tk sooner or later, as we can see here, sooner more than later. The car accident just made things go quicker.
I feel sorry for Taku but I want them both to end up together. Huhu
I agree. It seems like the author will be doing the “gets in accident and realizes how much I need and love u troupe” which I believe will make them end up together. Personally I don’t like Jowoon and Haesoo together but tbh I could see it coming from a mile away
Haesoo realized he can't live without Joowon before the accident, exactly the moment he saw that picture. The accident just made him confessed sooner xD

They already confessed each other at the hospital, they're together now
The reason why he chose to talk to taku happened before the accident happened hun, even if the accident didn't happen they would have end up together and no one can fucking separate them
I bet the reason why they'll be together again is because of the car crash
