[DeepL Translation - needs review] Volume 1 Introduction: One day, a postcard with the lyrics to a love song was written on Serina's desk. It was written by Mizukawa-senpai, one year her senior. Serina wants to get close to him somehow, but he is extremely cold and clearly has no interest in her. However, she finds out how clumsy but kind he is and confesses her feelings to him...? Every day is a thrill! A longing school love with a senior boyfriend!
(Translator: DeepL)
This was cute (the main couple communicates well and I like their relationship) but there's an annoying potential love rival that I don't want to bother with, so I won't be continuing the series.
The Japanese used in this manga is very simple and easy to read. It's great for learning a bit of slang and getting practice with casual speech.
