i think the tl gets this across great but for full context, the saying kuukou’s using here is transliterally ‘the buddha’s face thrice over’ which is an analogy used to say that even the most gentle of people will lose their cool when repeatedly subjected to injustices

but kuukou follows this up with ‘i’ll laugh it off no matter how many times’ which is him telling us no matter what life throws at him he’ll be positive thru it all and face with a smile
