I think this would be more interesting if there were a mystery-suspense element involved here. Like the 5 girls (who were all connected to New's character) conspired to kill him and hide his body. But their differences come into play as the story unravels.
Change2561 needs to experiment more with their themes (not that I wanna see historical dramas, but depends on the execution perhaps). I commend them though for coming up with strong female characters (though most of the male roles seem to be spineless). These are the dramas they released so far (aside from Club Friday):
Mia Noi - mistress-themed
Nang Marn - supernatural (but love triangle involving a married man)
Bai Mai Tee Plid Plew - LGBT-themed, revenge
Tok Kra Dai Hua Jai Ploy Jone - romcom
Samee See Thong - family, infidelity
Rong Tao Naree - friendship
Nuer Nai - infidelity, psychological
Talay Prae - infidelity
