Nothing to complain abt acting, but the plot is so immature, like a high-schooler's diary. Everything seems to take place in the family's living-room... It must be very low budget! Conveniently the ML gets paired with the adopted sibling, and the real sibling falls for the only family friend and also business partner. Just a drama abt 4 people! Not to mention they are all rich & famous, after rising from rags due to being genius or something! The ML becomes an IT graduate and businessman as an orphan while raising two younger siblings. The adopted brother is also a top student. The "dumb" sister becomes a well-known actress over night etc. The setting for this is literally an average house, too big to be realistic as an orphans' house, and too small for 3 accomplished adults.
Some side actions and characters are unnecessary, like the handsome doctor and the second fight with the gangsters.
This mini drama is saved by the excellent actors - special mention to the child actors!
Just watching out of boredom.
