We have a friend who's going through a lot right now, and I was looking at his tweets when I saw someone replying to some of them, and I realized that it's one of our friends.
I sort of checked his account and saw that he only has one tweet that's literally just "test", and the rest of his tweets are replies to the friend who's going through a lot. Usually his replies are just suggesting the dude to watch and read anime, specifically Isekai ones, but I found it really sweet.
That friend is probably the most dedicated person I ever saw from the group, and he tries to interact with the dude even if the rest gave up since it's a repeating cycle.
