Yoru ni Kin no Ame no Furu

Midori met Natsume near ginkgo trees close to Natsume's apartment during high school and has been in love with him ever since. Over the years, they became close friends, though Natsume remained unaware of Midori's feelings. Now that they are adults, Natsume is engaged and about to get married, leaving Midori struggling to move on and suppress his emotions. This proves difficult, especially as Natsume begins to notice Midori's odd behavior.
