As hiroki entered his house if he could call it that and noticed they where nor here'tch must be with that bastard again', so he went to his romm and open up his laptop to check the stock market(yes he has been doing stock trade and has made up to 20 million dollars), after done checking the stock market he checked how his online shopping page he created is doing (if u are wondering how they don't know when he was about to tell them that is when he found out what they have been doing behind his back and decided not to tell them).
He thought to himself it is time to expand the business, so he bought a building for the headquarters and told saki, Michelle(Micheal mom), kasumi and natsuku, professor shoko, Hana sanomiya, shiki Nakamura, Lisa (Nao mother), luna(ayumu mother) about it and asked if they could help him find employee they agreed and he made Nao mother, Ayumu mother and Michael mother the manager (he meet Michael mother the day he found out about what they done when he was considering to kill himself,she stopped him they talked he told her everything and she decided to help him get revenge p.s he found out she was Michael mom when he visited her and she was shocked it was her son who did that and promised to help him to the end and for Nao and Ayumu mother he told them what their child did, thy were disgusted and promise to help him) so It has been five months since he created the tech company, he also opened a boutique, hair salon and a shopping mall under an alias but the government knows about this and agreed (don't ask me why) so during those five months hiroki observed changes in his body he became faster, stronger, taller, muscular and a little bit smarter (making his iq 450 it was 300 before)
