Oda Shuuhei, a high school student, acquired Hero Skills in another world, defeated the Demon Lord he was supposed to vanquish, and returned to Japan. As he enjoys his school life using his Hero Skills, Hasumi Kana, the most beautiful girl in the school who sits next to him, tells him, "I took an interest in you, Shuuhei-kun, whose atmosphere suddenly changed" and they end up becoming class representatives together. As the season for the school's cultural festival approaches, Shuuhei and Kana are busy with preparing for their class's exhibit, crafting cosplay costumes, and other preparations. As the time they spend alone increases, Kana begins to be attracted to Shuuhei, who can do anything perfectly, and slowly but surely, the emotional distance between them starts to close, but... It's a sweet yet intense high school romantic comedy that starts over with Hero Skills and a steel-strong mentality.

Kido Shougo, a high school student who's hesitant about love due to not wanting to end up like his divorced parents, finds himself in a complicated situation. One day, he's confessed to by his stepsister, Yuina, and his childhood friend, Azusa, and decides to seek love advice from his reliable best friend and the class's "go-to person for advice", Mahiro. However, (I also like Shougo though...?) Mahiro was also one of the "heroines" in love with him!! Suppressing her own feelings, Mahiro gives advice as a "reliable best friend", but Shougo's clumsy responses only fan the flames of Yuina and Azusa's affections. Shougo, oblivious to Mahiro's anxiety, comes to learn all about love. Their consultation time: "You have to close your eyes when you kiss, okay?" It becomes an opportunity for Mahiro to get closer to Shougo──!?

Having defeated the love comedy protagonist Amada Teruhito's schemes twice, I realize my high school life has changed dramatically from my first life. I'm surprised at myself──to think that I, a mob, am now making plans to go to the beach with beautiful girls. While I'm looking forward to it a little──I inevitably get dragged into trouble as well. 「There's something I want you to hear. Make some time after your part-time job ends.」 A consultation from Kanie Kokoro, one of Amada's former heroines. Honestly, I want to ignore it, but since this is a "beautiful girl in trouble event", I want to eliminate the possibility of Amada intervening. Furthermore, the "Disappointing Prince" Tsukiyama Ouji's popularity is reigniting. But even though you've returned to being popular, why are you coming on so strong to me, a mob? You want to talk alone at my house? ...You don't like me, do you?

I've amnesia, and for some reason, I'm constantly being approached by three beautiful girls every day: a classmate, a childhood friend, and a female friend. A situation that every guy dreams of, it's enviable, right? ...Except for the fact that one of them tried to kill me.

All memories resurface, and the pure love of the three accelerates. To the point of being cursed. Kosai Meguru, who lost his memory in an accident, was gradually regaining his memories and former life while being torn between two girls who claimed to be his "lover", Tanzawa Shirayuki and Saikawa Mako. While studying, he is busy every day acting as Mako's manager and doing the household chores. Amidst this, an important memory from the past resurfaced during a date with Shirayuki, and their relationship as lovers was progressing smoothly. However, at that time, Meguru reunites with someone, and memories related to Mako resurface. They were so heavy that they could change the course of his life. The peaceful life of the once close three friends comes to an end, and everything begins to crumble, even if they try to maintain appearances. Love. Family. Immorality. Respect. Inferiority. Betrayal. Despair. Pleasure. Hell. What is love... what is sincerity... and what path will the three choose──
