haluuuu i just read racing hearts! it was a nice read, honestly. likeable si astraea and she's v interesting, tapos ang ganda rin ng premise ng story. hindi ko nga lang ma-differentiate pa yung ibang characters huhu maybe you could work on the characterization, like highligjting their distinct features para mas ma-differentiate sila ^^ but overall it's nice!
ps. sorry ang tagal kong magbasa huhuhuhu, i had to put down my phone multiple times cuz i'm not feeling well today !! D':
