I believe that that Houjo liked Akihito first; he told Akihito's brother how he admires his motivation at work and has high hopes for him but since he is his subordinate he went to his brother ( who made the first move) as a substitute and eventually fell for him. http://www.mangago.zone/read-manga/1_2_cigarette/uu/1_2_cigarette-chapter-1/26/.
Can anyone give me an explaination about these:
1. Do Houjou-san like Akihito first or his brother instead?
2. Do you guys think that Akihito is the one who have become a substitute for his brother or Kenichi san who is actually become a substitute for Akihito?
