Wait, how do you send someone a heart on sky: children of light??
Hi sorry I didn't see this but in case you still need it answered, when you friend someone you have to unlock the second candle slot (the high five) and then from there you can either offer a heart for 3 candles from the tree
(I'm not friends with this person so nothing unlocked but if I friended them then the first set of stars would be unlocked, you'd have to unlock the next one up in the middle to unlock the heart gift)
Another way to send hearts, once you have them unlocked with that friend, is right from the home space
When you're here, tap that bottom icon with the star to go to your favorite friends constellation (there can also be two more of friends on either side of this depending on how many you have)
From here, tap on the name of the friend you want to send one to
And you'll get this menu, that icon with the heart envelope is what you'd use to send them a heart from 3 candles for them to grab with their light
One thing to note, you can only give a friend one heart a day so if they already grabbed one that day from you you won't be able to send one again until the daily reset
