It's the feeling you feel only once a month or probably every day when you watch BL dramas.
Surprisingly, I am happy right now... Ha! Sike! I'm sad again. Never mind.
"happy" is defined as:
"a state in which one is not, or not at all, unhappy; it is the result of the best disposition in us to seek pleasures; it is a matter for regret or praise."
Smartie AI : Are you happy?
Your partner : Do you like doing this?
Your partner: Yay, you found someone more intelligent!
You: Are you happy with your AI partner?
when your happy? i don't even know why you looked this up.
