After the death of Manjiro, his younger brother. Shinichiro's eyes lost their brightness, and the once-gentle, smiling man was suddenly quiet and aloof.

Being a good buddy, you always paid him a visit to see how he was doing. Because Shinichiro genuinely loved his younger brother, you felt pity for him

Shinichiro was silently sitting on his room with a dull look on his face and smoking "come home quickly" he hung up the call, he was frustrated cuz you didnt come to see him today.
