I Thot You Was a Toad's manga / #inferiority complex(3)

What appears to be a standard half-brother x half-brother incest story acquires suspense when it looks like Masayuki, the heir to his father's company, is being deliberately targeted and sabotaged.

A fellow's inferiority complex with his deformed clownfish. This story veered from light to dark, comedy to drama and back again so quickly, it gave me hiccoughs, and there are quite a few moments of high comedy and intelligence, but I'm not sure I can reconcile the seriousness of the crime, which seems to have been used as a plot device for dramatic intensity, to the slapstick of the opening and the post-climactic resolution. WTF, was that supposed to be a comedy?
