Why Am I Still Everyone's Dream After Choosing to Slack Off Reborn?

[Magic setting, past and present lives + universally adored heroine + multiple female characters + no male lead] First, a disclaimer: the heroine is admired for things like friendship, not romance. There are no important male characters, and some male characters are portrayed unfavorably. If that bothers you, please don't read. A modern fantasy world with magic. Many characters have their quirks. Early on, the protagonist has serious psychological issues, constantly puts herself down, and struggles to communicate. She will change over time. A few characters have very little sense of morality. Synopsis: A hundred years ago, she perished alongside the Demon King. For some unknown reason, she awakens once more and is given the name Long Xunnian. But she never wanted to wake up, and no longer believes she deserves anything. With a cruel attitude, she pushes away everyone who offers her kindness, thinking that this will let her die alone once again. And yet The red-haired idiot says, "You really need to be more careful. You'll get hurt! Looks like you still can't do without me." The bald fitness fanatic says, "Your body is seriously out of shape. Don't even think about slacking off. Come running with me." The shy girl in glasses says, "I can tell you're a good person." A good person? She's just a useless, bad-tempered wreck who can't do anything. She shouldn't be trusted again. She shouldn't be allowed to feel warmth again. She's completely different from the person she was in her previous life. But the number of companions by her side keeps growing. Dragon: "I won't lose track of you again this time." Elf: "Look, this time I'm just like you." Many of her old friends: "Welcome back."
