Ch 93 and i still couldn't figure out who is the bottom yet
Alert Spoiler
based on the novel.
at first jiang cheng is the top, simply because gu fei let him be. both virgin and yeah even Jiang cheng think he is suck for that.
later on another occasion (the second time) gu fei being the top, and jiang cheng ask him, if he ever being the top before. since that day jiang cheng should admit gu fei is more suitable for the top
(≧∀≦)
but this story more about their find a way to fix their life, get a good treatment for gu miao. their being naughty is really rare to see
To give you a straightforward answer : they are a perfectly balanced couple, and their dynamic isn't a "I ask, you do." type of shit.
-> They both have their well fleshed out personality & story, w/each advantages in different situation. They always manage to work around any difficulties they might find, together.
Don't.. sniff..end sniff...
