It was the last time I drew and the first time I drew. I ended up doing a drawing over the end of the current year and the start of the new one.
描き納めと描き初めです。描いてる途中で年末をまたいでしまいました。
A wish you a happy new year.
新年明けましてよろしくお願いします。
The contents of the can are intended to be amazake. It's a traditional Japanese drink made from rice. However, outside of Japan, I think that drink isn’t very mainstream, so you can replace it in your mind with a drink that can be enjoyed hot or cold in your country in your country.
缶の中身は甘酒のつもりです。日本の伝統的な米の飲料です。ただ日本以外だとマイナーだと思うので、その国のホットでもコールドでも使える飲み物に想像を置き換えていただいても構いません。
