Fierce as in: mysterious, cold, dark, action packed, swearing,
able to fight, athletic, has scars of the past. That kind of thing?
Like major action characters in american action flicks?
Guai guai as in: Submissive, a sucker for rules, wussy, buying her
flowers and gifts to win attraction all the time, talking politely,
telling jokes all the time, smiling all the time, fooling around
with flowers and 1960s haircut. That kind of thing?
Depends on the girl. But most girls prefer the fierce type for
flings and short term relationships, it is mostly these kind of
guys who cant hold very high-paying jobs, and it is these kind of
guys who die early.
Long term relationships with homes and offspring makes the girl
consider the guai guai type coz they are more reliable. But during
the rs, the girls with a guai guai bf will fantasize about fierce
guys.
That's my take on it mate.
