yeah, rock sentimental kinda song.
i asked my friend to ask his gf what song it is.
the closest thing i can gather is "Sam Boon Kan"
and my searches show nothing close to it.
i don't reside in bangkok but i go there pretty often 
eh what so lonely? time to make more friends and go out!
i've been there 4 times in 6 months last year.
this year i'll be going around 4th quarter, i'll be busy with my
thai language lessons
