Did you sleep properly with ちゃんと
Vocabulary Explanation: Do it properly with ちゃんと

During an overnight school trip, a classmate tells a ghost story right before bedtime. While everyone else easily falls asleep, Sakura is too scared to close her eyes. The next morning, when Sakura washes her face, Tomoyo hands her a towel.
- さくら:
- 「ありがとーーー」
- “Thank you!”
- 知世:
- 「きのうは ちゃんと眠れました?」
- “Were you able to properly sleep last night?”
Here, ちゃんと refers to sleep as one should, rather than being awake all night.
