Orphaned at a very young age, Gui, a fourth-year engineering student, has had to work hard and earn for himself for as long as he can remember. Still, through the test of time, he still has a soft demeanor and a smile on his face. Solo, a freshman music student, has everything: money, fame, good looks. But he lacks a smile. After his mother’s early death, he lost his happiness. Nothing could fill this missing hole in him until one late rainy night he stumbles into a café for coffee. At that moment, their two worlds collide.
