Takeru Sato is called the number one "co-star killer" in the industry, and has been previously linked with Satomi Ishihara (27), Atsuko Maeda (22), and Ryoko Hirosue (33) -- all of whom have been his co-star at some point in his career. Sato, however, has never been cast alongside Mori in the past.
"Takeru-kun has a lot of friends from within and outside his agency, and has a lot of common friends with Kanna-san. The two suddenly got close to each other as they kept bumping into each other at parties and such.
Kanna-san was raised in a family that constantly moved locations so she has a frank personality and can easily get along with anyone. And not to be fooled by her beautiful looks, she's like one of the men as she never gets ashamed to eat yakiniku or ramen by herself, has strong resistance to alcohol, and never holds chit-chats about love and romance which every other girl loves to do." - (common friend of the two)
This actually isn't the only time the two were caught spending time together. There have already been reports that the two started getting close to each other around the time Josei Seven reported about Sato and Hirosue's illicit affair.
"Takeru-Kun was so sad at that time since he couldn't see Hirosue anymore, and was really down. Takeru-kun then sent a message to all his friends via SMS and LINE to gather them as he was the type who'd vent out all his frustrations and complaints, but everyone was busy and they couldn't make their schedules meet.
Kanna-san though, would always come whenever Takeru-kun called -- whenever, wherever just to hear him out. Kanna-san even started saying 'Let's invite Takeru-kun over!' when she's at her own gatherings with her friends." - (common friend)
And it also seems like Sato has been showing a side of him to Mori which he has almost never shown to the other women he's been with.
"Takeru-kun has always been the type who wanted his partner to fawn on him, but he's the one fawning over Kanna-san. Kanna-san is an extremely positive-thinker who basically has the mindset that 'I'm really blessed and happy right now' so she never dwells on any problems. That's why Takeru-kun forgets all his troubles whenever he talks to her and finds comfort in her." - (common friend)
