To me, that kind of face can be interpreted as: "I would love that, but I have a life/family and you have a life/family, so it's impossible."
What I was kind of confused about was the 'If you stay till morning, then I'll leave my life behind' offer during the one-night-stand. Did he forget that his boss said that, or was that a flat out rejection as well? His stunned face made me think he had forgotten...
The boss said it 8 years ago when they were both single (and possibly in love with each other).
At the time, uke didn't stay, so the boss hot married to his wife. Then uke also got married. Both had kids...life happened.
The boss is saying, he would have left his fiancee back then but he can't any more coz they are both family men. U can dump ur gf or fiancee for a liver, but u can't leave ur family for an ex-fling.
WHAT DID THE LAST PANEL MEAN?? THE BOSS REJECTED HIM?? OR DID HE THINK ABT IT AND WAS TORN?? SOMEONE HELP
