I have watched an asian tv drama long ago and i liked it. I am not 100% sure that its taiwanese and i watched it before in ViKi Rakuten App on android.
It is about a girl who was rich and her family owns this perfume corporation/business. EP1-2 was about her getting wed to a guy, but she rans away and hides from the wedding. In the wedding venue the male lead is taking pictures and stumbles with the girl/bride.
Later the girl is found to be hiding in the back of the van of the Male lead when he goes somewhere hill side. The girl comes rolling down and hits her head. They go to the hospital and the girl after waking up gets an amnesia. They stay at a hotel/motel for a while.
The guy is introduced to be somewhat okay in life. His parents owns a tea shop, they sell leaves or brews/beans.
Very later in the drama the girl regains her memory and avoids contact with the guy and pretends she doesn't know him and gets back as the owner of a company. The guy pursues the girl but then just makes his dream scent perfume and gets rich.
there was this character named Xiao tong or brother tong male side character
two more side/main characters. The Male is a psychiatrist who likes to shout in the toilet cause it releases the things he got from his clients and always reiterates to the girl his interested that his appointments are private. The girl is this prim and dazzling fashionista that dated the psychiatrist guy for a short period of time and after her breakup with him she decides to somewhat seduce him into liking her again either by making him jealous or through her fashion style.
Can not find it in Viki Rakuten anymore. But i remember its poster having a blue / sky blue background with a clock behind the characters, one or more characters are sitting on a teacup. The opening for it has the theme of rewinding the time so like at the start everything is FORWARDS and then it goes back to the start
