At tha last page their eyes look tired, exhausted, and various emotions too. I can't feel happy for the uke at all. They actually look a little bit like this (⊙…⊙ )

I feel the same......
I don't really see it as them loving each other but just taking the next best thing......nanami taking the twisted heartbroken love of isugai..? (not sure about the name) as a substitute of the love he never felt...
And isugai taking nanami as his beloved which he lost......
That's my opinion only (〜￣△￣)〜
This can't be the end. Words can't express how much I love this manhwa and how much I love min woojin and especially taemin. You can't just take this all away from me. （/TДT)/ I want more of them and more of the story. I want more explanation as to what happened. This ending leaves me many questions （/TДT)/
