Chika and Yumiko are to do more promos as Heart Tart. But before their first guest appearance, they get some nasty comments from Mekuru. Even worse, Yumiko has to admit that she has a lot to learn to get to Mekuru's level of skill and knowledge.
We just happen to attend the same school.
.تصادف أنّنا نرتاد نفس المدرسة فحسب
Wir gehen nur zufällig zu derselben Schule.
Solo somos compañeras de clase.
Frequentiamo la stessa scuola 
per puro caso, tutto qui.
A gente só estuda junto por coincidência.
Мы просто учились в одной школе.
