This series seems much more grounded compared to many others on this site. I personally don't think there will be any romance but not because of anything complicated and more for boring practical reasons.
This series follows a female editor at a Japanese publication company, females in Japan typically avoid romance in the formative years of their career due to Japanese culture. Combine that with Tanaka being Toda's editor and thus being in a position of power can lead to an unbalanced power balance in a relationship.
Tanaka comes across as too professional to do something like that in a series as realistic & grounded as this.
