Elfy:
Out of curiosity, what do you guys consider a good couple or make a good couple in BL's?
First, to be really invested, I need to feel quite attracted (= heart goes pitter-patter) to at least one, preferably both (e.g. Tutor and Yim).
Second, acting ability, both individually and together (e.g. Fourth and Gemini).
Third, chemistry, intimacy, being comfortable with each other, etc. (e.g. Keng/Namping and Thomas/Kong, the two couples that so naturally emerged from "DMD Friendship the Reality").
I'm not a very snoggy person, so snogging and tongue-sucking skills aren't particularly important to me.
Disclaimer: In case of sufficiently irresistable cuteness, the second criterion may be overlooked.
