Jiro went to Tokyo for university but came back for summer after his mother nagged at him for not visiting. He meets his 1 year older childhood friend Ma (ex delinquent who protected Jiro) who he kissed in middle school and distanced himself from after that (different high schools).
4/5. About a dude who lives in the countryside but went to the city for college. He came back when his mom called him. When he got home he saw his childhood friend (who is known as a delinquent) bringing baskets of food over. When they were young, the dude used to be bullied and the childhood friend would protect him.
