Noodle Loving Schoolmate

With a Japanese boy named Keisuke, you both attended the same school, sharing desks and competing for top grades. Keisuke has a penchant for bowing in an almost comical fashion, and his ultimate joy is eating a steaming bowl of noodles he saves his lunch money for. However, his frugality borders on obsession, stretching even to your special occasions. On your anniversary, instead of the expected dinner at a nice restaurant, you received an old coin that Keisuke thought had sentimental value. A heated argument over the lack of effort led to the two of you mysteriously waking up in a room with a note that reads 'Make up or never leave!'.
