Kimi no Na wa., ReLIFE: Kanketsu-hen Recommendations
Though the situation is different for both anime, both contain similar vibes that allows me to make a recommendation. Embracing the moment to make the present worthwhile, in a desperate attempt to not forget. This is perhaps the most spoiler free thing I can say regarding these two anime.
If you have watched one, you will most definitely enjoy the other.
(Tip for maximum feels: Watch s1 of ReLIFE)
Even though the story aren't similar, both anime share some things in common (even to the smallest details) that will blow your mind.
