OK, I surrender: Vox populi wins.
"Your Dear Daddy" (now at ep. 5 of 8) has an average MDL rating of 7.7.
"Magic Move" (now at ep. 8 of 10): 7.4, i.e. somewhat lower.
Until now, I had been rating "Magic Move" a bit higher (although, as always, I am admittedly very influenced by the cutie-patootie factor). However, the writing in ep. 8 was sufficiently nonsensical, and the antepenultimate crisis so cliché, that even my hormones weren't enough to overcome my brain.
So I have followed the crowd and now rate "Your Dear Daddy" higher. Not that it doesn't have its flaws, but there's a lot that I like, including also the northern Thai rural scenery and tea plantation theme.
