Tsubasa is ordered to score high on exams, so when the lovely Rena offers to tutor him, he accepts. He soon realizes that Rena expects a reward for her help. Minami spots them together and is thrilled at first, but then starts to feel very uncomfortable.
and then you even helped 
me study over the weekend.
ثمّ ساعدتني حتّى في الدراسة
أثناء عطلة نهاية الأسبوع
sondern unterstützt mich
auch am Wochenende.
et même le week-end,
par téléphone.
ti sei anche offerta di continuare nel weekend.
mas está até me ajudando
assim no final de semana.
а до этого и в школе
помогала готовиться.
