This week I learned five new words through my work and watching the Japanese drama: この世界の片隅に。(konosekai no katasumi ni)
刻み値 “kizamichi” increment, step value (noun)
お盆 “obon” the tray used to carry food and drink at a restaurant (noun)
会計 “kaikei” the bill at a restaurant (noun)
複雑 “fukuzatsu” complex, deep (adjective)
チャラチャラ “charachara” messing about, not serious (adverb)
〜なくて済む “~nakute sumu”
I read on another blog post that it means “get by without doing” but I think it depends on the context. However, I consulted other Japanese people and I found it can also have the emotion よかった。 “yokatta” or glad that something happened/didn’t happen. For example:
The window was left open, but luckily the cat didn’t fall out.
