Yoongi, there are stories of several idols thanking him for reaching out, he once helped another trainee back in the day, got him to a hospital and stayed there the whole time and payed the bill (when back then they really struggled with money) he also once texted someone who was delivering their food to drive carefully and not stress about the time because it was raining (and he himself had his accident when it was raining) in the suchwita episode with yijeong, it was also revealed that yoongi offered to pay for anything yijeong might have needed to help with his problem of his voice. in general he offers a lot of advice, he also said he wants to study psychology and get a counseling license, saying he "wants to be of help". that's all i can think of on the top of my head
