Kazuya learns that Kuribayashi's been down in the dumps and tries to figure out how he can help him.
Not like I would've realized 
if they hadn't told me.
لم أكن لأعرف لو بقى صامتاً

Se fosse stato zitto, non mi sarei accorto di nulla.
Se eles não falam,
eu nem ia ficar sabendo.
А мог бы молчать — никто бы не узнал.
