arranged marriage, love after marriage

arranged marriage (main and side couple). this is one of my favourite dramas <3

they both have their reasons for wanting to just get married to somebody, so they go on an app, find each other, and decide to get married. this drama is very light hearted and stress-free.

she goes into a fictional universe where she is the empress, married to ml, but he hates her and wants to kill her.

scriptwriter accidentally enters her own script as the third princess, a side character who is supposed to die by the hands of ml on their wedding night. she enters the world as she's about to marry ml. i love this drama. <333

arranged marriage, but fl goes in place of her sister. there was a misunderstanding which made people think ml was dead, but he's not.

a guy wakes up in the body of a crown princess, married to ml. ml doesn't like him/her at first, to say the least. haven't finished this one yet, but i still plan to.

same story as above. haven't seen this version yet.

i don't remember this one, but it seems i've watched a good amount of it... based on the desc. i'd assume it's arranged marriage.
