Just like NLB in the WCRG ML is sickly and FL though of treating him good until his last day and was looking forward to returning to her home. In both drama FL starts packing her bag when things start going south.
in Destined, there is a really good focus in character development for both of the male leads. In both drama ML is same and is also focused on politics. In my personal opinion if you like this drama, you'll love Destined.
Even though BTIMFL is not a high school drama, both of the series has main leads living together in secret and slowly start developing feelings for each other.
