Hello Hayashi :).  I hope you don't mind the correction.  Just few problems with verb tenses and plurals.  Especially when verb changes tense when the noun is a plural.  Very natural mistakes by Asian English learners since there's no real plural usages in most Asian languages.  Keep up the great job :) If need any help in the future let me know :).
