I never actually played this game, but it's art style is very recognisable. So, according to the screenshot I found that would be Jana from Lands of Lore.

Yes, it's your turn.

Who is the gentlemen on the left (I don't think the one on the right ever had a name ;-P)?

A little hint.
He is from a Korean PC game from 2001.

No one? A new hint then.
The game combines 2 different genres, but in short the design can be described as "love letter to Blizzard Entertainment". The sequels would play very differently and would only come to Xbox and Xbox 360 (until the latest and possibly last instalment, which would come to PC and PS4).

The way he looks in game.

Ok. Maybe a full screenshot straight out of Mobygames may help ;-).
You have all the information you need now, at least when it comes to identifying the game.

Likuku

Correct :-). Your turn.

Ok, let's see if someone can identify main character from cringy game I played sometime during my childhood/early teens :D

New hint :3

Picture from game cover :)

*bump* and no idea...

That was enough information.
