不敢神经我怕入戏
[bù găn shén jīng wŏ pà rù xì]
'Afraid to Mess With My Nerve for Fear of Being too Much into Character' conveys that the person dare not express emotions excessively for the worry of getting too immersed in certain situations, which may reflect a rather introverted and self-disciplined characteristic. It may also describe an individual's fear of losing themselves or their rationality while facing feelings like romance or excitement.
