Hayami Shachou wa Kyou mo Suki tte Iwasetai

Shogakukan official material identifies the work as a completed newlywed romance whose central relationship is a political marriage between the female university student Fumika and the male Hayami company president. The synopsis explicitly says she loves him and he is determined to make her say she likes him. That is a concrete central male-romance mechanism and a male main-cast relationship, not a speculative possibility. The Research does not establish an F-level heterosexual end-state trigger, specific male intimacy act, NTR, coercion or bait, so E is the most severe supported grade.
