I don't like her role in tokyo dogs, but she is somehow cute in love shuffle.
I found an additional report from tokyo sports(a newspaper similar as the sun UK)
生田斗真と吉高由里子の手つなぎデート発覚！しかし、生田は熱愛を否定！
it is kinda interesting that the report totally ruled out the possibility of their dating, although tokyo sports is usually well known for writing negative stories about all johnnys' guys. :)
