SUNBURN The handsome foursome are all in an uproar once more when they are lead to believe that Sunako has fallen in love with their science teacher. Their theory is followed up with evidence: for one, the science teacher is quite handsome; two, Sunako has never looked lovelier: and three, Sunako keeps on sneaking out to see him.
