My Girl in White Dress

[No rebirth + no system + multiple heroines + first person + workplace + no harem + come one at a time] What? My ex-girlfriend, who I haven't seen for four years, is forcing me to make a choice between my current girlfriend and me? Then I directly choose to make money first and use the industrial resources left by my deceased father. I want to climb to the top of business step by step. If it is not possible, my girls in white skirts, come one by one. My heart is big and I can hold all of you.
