can be sued or not ?

Hi ask ko lang po ? Helping a friend lang.
1 year na po kase nakakaraan since nangyare.
yung friend ko po kase nag panggap ng babae sa game.
then may na meet syang tao taga ibang bansa.
then yung guy daw siya mismo nanligaw sakanya and and ang nangyare is sinagot daw nya. after that edi may relasyon sila .. nagkarelasyon sila for 1 year and ang 1 year na yun bigay daw ng bigay ng pera yung guy sa ibang bansa. which is bago sya mag bigay daw inaask muna ng friend ko if okay lang daw. Well according to the guy sa ibang bansa . sige lang daw sige .. i mean okay lang daw skanya. It means siya mismo nag kusa nagbigay and willing siya nag bigay.

Ngayun daw iniwan na nung friend ko yun nagbagong buhay na.
ea nakita nung guy sa ibang bansa yung real fb nung friend ko.
chinachat daw sya na " wala daw balak kunin yung pera sakanya" pero parang ipagkakalat nya sa mga tao sa paligid ng friend ko yung ginawa nya.

posible po ba ma kasuhan yung friend ko about dun ?
which is 1 year na nakalipas since nangyare.
if posible, anung posible ikaso sakanya nung guy sa ibang bansa?
or Do you think na may maisasampang kaso yung guy sa ibang bansa sa friend ko ?

Your friend can file a case for simple coercion, but the same would be futile. The person threatening him lives abroad so our courts cannot have jurisdiction over him unless he comes here and gets arrested.

my friend has no intention to sue him....But on the contrary.. Is there a chance that my friend will be sued by the guy from abroad ?

I cannot answer your question since I am not familiar with foreign laws, particularly where your friend's friend resides. I guess the only way to know is to go there personally and check if a case has been filed. But then again, why risk it?
