Hi guys,

I ALWAYS suffer from the second male lead syndrome in dramas!

It leaves me frustrated all the time, because the 'obvious' male role just 'wins' all the time.

Does someone know a beautiful drama (if you have a J-Drama recommendation I would also be happy)

where the 2nd male lead 'gets' the girl in the end? I love myself some twist in a plot! I would be very grateful! 

you want spoilers? hehe
Over Time - Well, the second lead... I don't know how to put this without spoiling so I'll just say it. Er, he was hardly even a 'lead'.
Queen of Reversals - script was changed during the show to favour PSH. (Also apparently happened in 'How to Meet a Perfect Neighbor'.)
Last Cindrella

Also I think you might want to try 'Three Dads One Mom'. That one is not exactly a second lead thing but it will keep you guessing and the lead males are quite equal through the show.
@Fira miura haruma is just second lead in Last Cinderella??
@prettyin - I thought it was really ambiguous! I was watching it when it aired and thought that Tachibana (Naohito) was like standard first lead material. The direction that drama went to surprised me at least.
Flower Grandpa Investigation Unit ( its not really based around romance though its more comedy)
At the moment, only these two titles came to my mind:
One Well-Raised Daughter
Feast of the Gods

try these dramas (though some of them is already recommended here)

Pretty sure it happens in Prosecutor Princess too but the actual actor has a somewhat unclear sexual assault scandal so do with that what you will
