他会发光i她好耀眼
[tā huì fā guāng i tā hăo yào yăn]
The phrase translates as 'he shines while she shines brilliantly'. It seems there's admiration or envy regarding two distinct yet shining entities, maybe persons who exude charm or confidence. The small 'i' adds emphasis on oneself within the brilliance of the others or signifies connection ('and'), showcasing contrast between dazzling presence around oneself.
