This one doesn't match the title. It's about a two-dimensional romance with a confrontational path. [Poor] The poster doesn't see as many bl in front of me. This is the only two-dimensional romance that the poster can watch and loves to read very much. Lawson is a completely tsundere knight, beautiful and strong, while Annabelle, the tsundere eldest daughter, is very contrasting. She is noble on the outside and cool on the inside. She is a sweet little girl at heart. However, this attribute only occasionally leaks out from Lawson. She has no magic talent but is a super hard-working person [Spread Flowers]
I gave it five stars because I couldn't find a meal replacement. At first glance, the male protagonist thinks he is a sunny puppy, but in fact he is a dank and paranoid character who is very insecure. He approaches the female protagonist with a purpose at first, but accidentally becomes her loyal dog. The heroine is a legitimate princess, noble and brave. Not too long. One of the points in this article that stuck out to me is the interaction and relationship between the heroine and her younger brother (the prince, who will later inherit the throne). The younger brother is life to the heroine. As for why this is not spoiled, the younger brother doesn't appear much but leaves a very deep impression. He is a super sister-in-law, and he inherits the throne for his sister.
This is a sweet story. I read it a long time ago. You can read it when you are bored. The male protagonist in the side story is quite yandere, and the main text is about the daily love life of childhood sweethearts.
