If you could make your ending for this drama, what would it be?

TBH I 'd like to have seen more of Zhang Peng cuz those endings are weird! I kind of forgot 1/2 into the drama that it was a time travel. It would be fun to have them both switch- so this is their reincarnations and have the ML be the girl at the pool.  OR someone else cuz they do not show that many people in the present that it is hard to pick another switch.
