Ah! What happens to Jun?! Now I'm so curious I hope it's nothing bad...
Anyway, as always I really like this chapter. It's cute that Satoshi can never understand his two youngest brothers. It's the age gap and it's pretty believable too (I'm sure this happens in siblings with wide age gaps, as I found in the families I know in rl)
The tequila night is super amusing. I'm actually glad it went to the lighter mood. Sho is seriously adorable when he got drunk lols
