As reported last week, Taguchi and Komine visited Hawaii together. Although they flew there together, they took different flights home - Taguchi flew into Tokyo, and Komine flew into Osaka. Despite this, they caught the attention of the media. Neither gave any official comment.
Reporters waiting at the airport asked Taguchi whether this was a pre-marriage trip, which seems to be everyone's concern at this point. He gave no answer and seemed uncomfortable with the questioning. Komine is reported to have said, "I don't care about my career, but leave his career alone." Although Taguchi is young, since they have been dating for some time, it's not ridiculous to think that they may be considering marriage - but both agencies would have to acknowledge the relationship first!
SN still thinks this is a nice couple, although Komine might be a bit too old for Junno.
