I started the game at the start of 2021, and of course fell in love with it. Later on, I knew of the heart island chest existence, so I decided to save it for my husband who I had no idea who he was! After three years of playing I met and married my husband! He is a gamer who wasn’t playing genshin. I literally mentioned genshin with him on our first meeting to know if he knows the game or not. After a whole year of nagging for him to play the game, he finally did! He actually enjoys it very much and asked me just now if he can defeat signora using signora (my sweet summer child). Well, our wedding anniversary was a while back so I decided on the day the heart chest is finally due. Then realized his world level is too low for him to join me (rookie mistake) so I entered his world to open it together. Each of us chose their favorite character and claimed the chest! Sadly he claimed the chest before I could take a picture but here you go!, picture from his side :)
I saved the heart chest for my unknown future husband, five years later!
