Kensuke didn't even have breakfast this morning. But, already chasing with the Jeep. So, right now Kensuke has to be content with eating air and drinking only water. It's okay, Kensuke feels that he is a strong young man. His stomach will be full if he drinks lots of water.
It's also impossible for Kensuke to eat well when Kensuke doesn't know the fate of his twin brother at the moment. Then, not to mention Kensuke who still keeps thinking about his mother who disappeared in an accident. Kensuke couldn't eat well and sleep well as long as Kyosuke and their mother hadn't met.
The Jeep that Kyosuke had been following earlier, now stopped in front of a cafe.
