TW - Basically grooming in a way. MC is 17 when he meets the guy who is 28. When I read the sypnosis I thought it mean "Getting ready for his entrance exams" as in he is about to take them so he could be a 18yr old high schooler and then I expected the ML to be 21-24 but there is a 11 year age gap!!! He even knew he shouldn't and still went for it. Not only that but in chapter 2 there is a scene where the little kid (Not sure who but I'm assuming it's the MC's little brother since Iskimmed through it before dropping it) kisses the ML in the lips and snuggles with him. That just givese off Pedo vibes and the ML is a complete stranger to that child so it's not cute whatsoever and even if they were family it would still be weird.

The author did a horrible job with the time gap and pedo vibes. I don't recommend, and sadly the MC is beautifully drawn, a shame such nice art is attached to a bad story.
