With Atushi’s sports day coming up he needs a family member to participate in the family events.  Will it be Mom with her sudden hip pain, Dad with his knee acting up, or Atsumi?
I even have to participate 
in the family events,
Para colmo, tendré que participar 
en el juego de padres e hijos,
Encima voy a tener que participar en los juegos entre padres e hijos
Tenho até que participar 
nos eventos de família,
