go all by yourself? really?

i wonder if he said that because he felt like wooyeon wouldn’t be part of his future... i mean both of them had never confessed to each other, or anything like that right? i’m not sure

I didn't understand that. When you're in dépression, people around you could be very attentive, it's you and only you who can help you, if you base all your life and happiness in someone, the same thing with the other hyung will be, a very suffering period. So, we have to base our happiness on the people that matters the most, ourselves.
