After Becoming Kirihara's Protective Sweetheart

The protagonist traveled through time and became an egg After breaking out of his shell, he discovered that he had become Kirihara's protective sweetheart. And it is the image of a black-haired little devil with devil horns That's okay, at least it's pretty and cute, isn't it? However, who can tell him that as Kirihara's sweetheart, why can all the main players in the tennis club see him? Kirihara recently discovered a big secret There was an elf beside him who looked very similar to him And only he can see this elf, no one else in the family can see it. This elf can even help him improve his tennis skills This made Kirihara, who loves playing tennis, ecstatic and felt that this was a personal gift from Santa Claus. So, thinking that only he can see the elf, Kirihara takes the protagonist to the school and tennis club. As a result... I was discovered as soon as I walked into the tennis club. Sanada: Kirihara! Even though he was late for his club work, he brought a cotton doll to the tennis club. He was so lax! Train twice as much! Nioh: Pfft~ I didn't expect Akaya to also like dolls. Where did you buy this little guy? It's quite exquisite. Marui: Can't you tell? I didn't expect that this guy Akaya would like dolls, and even put them on his shoulders and bring them to the school. Yukimura: It's very cute, Akaya, can you show it to me? Kirihara and the protagonist, who were surrounded by everyone, froze in place and did not dare to move. Neither of them expected that they would be discovered by others. Purpose: People who work hard should not be let down
