Have seen with 〜たことがある


三ツ星カラーズ » Volume 5 » Page 115

Sacchan and her friends come across a torn piece of paper with 「あたり100」 written on it. Thinking it may be for a 100,000 yen prize, the girls head to the shopping district to redeem it. Along the way, their friend Nonoko says she doesn’t recognize where the ticket is from, but Sacchan’s mother says it looks familiar somehow. Kotoha admits it seemed familiar to her as well, but she thought it was just her imagination until now.
