"I have a question about The Eternal Love, I read the plot and it seems that the guy falls in love with another girl in his wife body. I’m not into that unless he falls in love with the wife at the end? Does this makes any sense LOL. Dw you can spoil me. I have to know if there’s a happy ending for the couples or not :)"
Future girl transmigrates into past girl's body and they switch from time to time. The prince falls in love with the girl from the future and she him, while the girl from the past is in love with another prince.
The switching doesn't happen too often and all the fun rom is happening with the future girl. While the past girl is mostly tragic, as she has to live with consequences of what the future girl does with her body with the prince ;) lol. Anyways, highly recommend it! It has a happy "ending", sort of, or more of a promise of future adventures as season 2 will start airing tomorrow, yay!
