わずか一杯(いっぱい)しか食べられず(たべられず)、「夢(ゆめ)を願って(ねがって)いるときの方が(ほうが)幸せ(しあわせ)だった」と気づいた

Goi was full after drinking only about a single bowl of the served yam gruel. The rest of the vast amount of gruel was licked up deliciously by Toshihito's pet fox. Goi realized that he had been happier back when he was only wishing to 'eat my fill of yam gruel,' feeling a sadness that his dream had been so easily realized.
