Misleading ML

Unexpected ML
The male lead seemed to be obviously the prince, but very unexpectedly he ended up being the '2nd male lead'.

Unexpected ML
I dropped this ages ago but I remember thinking that the male lead would be the dark haired knight. However it seems like while I was gone the blinde wizard became the main lead.

Unexpected ML
I believed the prince would be the male lead as it would be quite typical but WOOW he wasn't! The male lead is the cute wizard, highly unexpected but highly appreciated.

Unknown ML
(NOVEL SPOILERS)
Had I not read the spoilers I would have expected there to be no male lead until basically the end, but it ended up being a polygamous ending with 2 of the Binahs (which didn't make much sense because the author only chose them as the only 2 conventionally hot and young looking male Binahs and it was also quite sudden, but well I love unexpected endings anyways)

Unexpected ML
You would expect the friend (the roommate from the description) to be the male lead, but the mc actually ends up with the '2nd male lead'.
