I typed it up as:
私鼓田ミナレは麻藤さんが私との会話の内容をなんびとに伝えようと文句を言いません。
グチ聞いてくれてありがとうアイシテル

If it’s in fact a kanji, it’s eluding me - what do you guys think?
P.S. Would be happy to know about any other mistakes in the transcription.
P.P.S. Funniest moment so far of a show that’s showing promise
Edit: Alternate shot of what’s under the thumb:
