The M.C. is meek at best.
In every single situation he is put in, he defaults to thinking he is in the wrong. He doesn't explain anything to anyone, and in the few situations where he needs to make a decision he second guesses himself multiple times. Then when the natural happens, the pushback and questioning, instead of just saying why he thinks the changes he proposes are needed, he starts thinking he is wrong.
I made someone upset? I was in the wrong. Not the way I did things, how I said or presented it, but I was wrong. Sister of one of the workers comes and makes a mess? I was wrong. That she is bullying me or that this could be awful for the business? No thoughts, I was wrong. What about...? I was wrong. Wrong about what? I was wrong.
What a fucking doormat. He is treating everyone else like a japanese salesman treats his superiors, and not just externally, internally too. At least the salesman has to take it in order to keep his job and wants nothing but the worst for the boss, our MC is honest in his cheek spreading.
'Situation ---> I was wrong'-pipeline is so strong that I can bet my nutsack 80% of the text in the game is internal monologue, with a 30/40/10 split of mulling over the situation, chastising himself for everything, and being horny. In that order.
It's a complete chore to play through a situation where just acting like a normal person would remove or reduce the drama to large extent. It's not even a good flawed character that brings about discord due to his characteristics, he doesn't exist for anything else but to say sorry. It is not interesting, it is not engaging, the only emotions it provokes are disgust and anger.
I completely skipped the last third of the game, the sister talking to the MC for a long time transitioning into idol concert. I would be amazed if it wasn't 80% angst and 'I'm sorry', with the remaining 20% being the sister talking him into doing the concert.
Anyways, game is too short and starved of content, the MC is completely unlikable, the story is just pants-on-head retarded, the H part is almost non-existent, gameplay/music/visuals are bog-standard VN stuff, nothing to write home about.
It's a cashgrab, low-effort garbage, that, and I repeat this, could only be made by a person that is the same as the MC. Even if it was a charming little game with no problems when it comes to content, I would be hard-pressed to give the money they are asking for. Avoid this.
