Rinsama_'s manga / #Poor(1)

I love Kotetsuko's every work, this one included!! This one is about a poor young boy who has an unfortunate life. First, his mom ran away, so he was left with his drunk dad. However, his dad is very kind towards him and encouraged him a lot. However, his dad passed away, so he was left all alone.. One day, he found out that he was in 5M debt left by his dad.. With him being a hs drop out, poor, and a conbini worker, it was hard to pay it all back... That's when he met his hs friend.. So his friend offered to help, but he refused. He's the prideful, serious, and strong type of person. It's very cute and nice. But since his saving was all used up to pay the debt, somehow he asked to stay at his friend place reluctantly.. Anyway, rhe friend confessed. This guy is also weird.. Probably because he has rigid grandpa, so he's quite straightforward and a bit of an airhead..
