To anyone who wants more of this, please read The Dragon, The Hero and The Courier by the same mangaka. It has the same feel but different setting and is really good.
I'm kinda happy the romcom thing never came to be. I'm not a fan of romcoms with too many heroines since I generally want the all to win in some way and the OTP always ends up leaving a bit of a sour taste. Sweet romance and relationship story without a whole bunch of rival drama is generally nicer.
A nice little story about historical girls coming to our times. Pretty funny and chill while also being loaded with information on each character's respective periods, it's a nice read for those looking for a nice way of killing time.
