is this used to describe an older brother?

mu weiwei's heart skipped a beat and she stopped.

"what did you just say? can you repeat that?" fu linchen smiled gently again.

mu weiwei's thoughts were alternating between 'smiling so beautifully' and 'smiling so creepily'. cold sweat broke out on her forehead. she opened her mouth and asked, " say it again ... what? "

"you just said that i'm the most ..." fu linzheng said.

"the most affable and friendly elder!" mu weiwei's memory returned and she thought that fu linchen did not hear her clearly. she quickly repeated the flattery she had just said and emphasized, " "really, i don't think i'm lying! brother fu, you care about me more than my grandma ..."

in other words, she was even more talkative than the eighty-year-old grandmother mu.

mu weiwei secretly cursed in her heart, but it stopped when fu linchen suddenly let out a cold snort.
