The Right state: the Left’s poem seems a bit too young. The Left state: ‘Simply was I used to playing’ (nani to naku asobinarenuru) seems rather prosaic diction.
In judgement: although the latter part of the Left’s poem and the initial section of the Right’s are both pleasant, the Left’s use of ‘speak’ (oto) feels unnecessary. The latter section of the Right’s poem seems particularly good. It should win.
