Ok, after having gone through the entire thing, I've got just one question:
What the hell happened to the girlfriend after this? Did she vanish from the ends of the earth? Did the author forget about her? Did he ever had a plan with her he couldn't use?
Don't get me wrong, I know it is more real to not have them reconnect again, but it's just so weird to have the ex in a "drama" have a fully fleshed backstory & personality just for the girl to never come up again.
I guess I wasn't expecting such realism.
