Ano Hi no Kiss wo Mou Ichido
Complete | NANATO Nana | 2023 released
Re-encounter and heartache caused by lack of communication. I liked that they had full lives in between, both were married with various degrees of happiness, and managed to find each other again and fix their past mistake. Even if it's an extrovert-introvert relationship, both are bad at expressing their real feelings and seem opaque to each other (which, apparently, is an attractive trait to have).
