We are brought back in time to when Yume and Mizuto were once a couple. A time when neither of them could control their nerves in what was their first ever relationship. Having already held hands and kissed before, the young couple are eager to take the next step. Spring break passes, however, with neither able to make the first move. Upon entering their third and final year of middle school, the two are regrettably put into separate classes. Alas, unable to spend as much time together as before, they both begin to grow apart.
When both Christmas and Valentine's 
passed by without any contact,
عندما مرّ كلّ من الكريسماس
،والفالنتاين دون أن نتواصل
Als sowohl Weihnachten als auch der Valentinstag
ohne jeglichen Kontakt verstrichen,
Cuando pasamos Navidad
y San Valentín sin hablarnos,
Cuando pasamos Navidad
y San Valentín sin hablarnos,
Puisqu’on s’est pas contactés
à Noël et à la Saint-Valentin,
Visto che a Natale e a San Valentino
non ci eravamo nemmeno sentiti,
Já que não houve contato no Natal
nem no Dia dos Namorados,
После Рождества и Дня святого Валентина,
прошедших вот так,
