Well, before Haruna and Ryusei proved their good chemistry in Kikazaru Koi, they were so nice together in this Shiro to Kiiro drama even though with much fewer screentime. Both dramas also have similarities for a story about food/restaurant with daily struggle of the characters. There are some "love competitions" between the characters, but they also show good friendships & nice relationships. These two dramas also bring good stories about hard-working spirit to make dreams come true.
