The couple were seen again the next morning at around 8:30am, when she saw him off from the back door of the apartment.
The young actors, both 24, acted in TBS drama 'Ooku~Tanjou~' which aired in October last year. They had some love scenes together. According to the article, Tabe was impressed by Kubota's acting abilities. Net reactions have so far been favourable with comments like,
"They look good together."
"Their face sort of look like each other, so I think they suit each other."
"He's that kid who can really act. He played a lunatic in Joker. Both of them are good actors."
"Oh, Tabe-chan got herself a boyfriend. Congratulations!"
"Lately there's hardly any news of refreshing couples like this. We have Gakky dating that one, shotgun marriages, DV couples getting married, Yaguchi cheating, just things like that."
"They're a young couple, but they somehow look composed."
"I'll tolerate it since it's Kubota-kun. Maybe I'll even cheer them on."
"Sakai and Kanno got married from Ooku also, maybe it's the atmosphere from the filming."
In the past, Tabe has made known her desire to get married while in her 20s. Kubota on the other hand, is said to be a late bloomer who falls in love at first sight easily but have difficulty in approaching girls. So far, variety programs and talk shows have avoided reporting their romance so there is a possibility that Tabe's agency is against the relationship.
