They are just the cutest ever!!!
A world where there is no prejudice against same-sex love or marriage, and male pregnancy is possible. This is Kaiju Academy, a boys' school in Tokyo. There lived a boy named Guest, the "Princess" of the school, known for his overwhelming beauty. In the spring of Guest's third year of high school, something wonderful happened: his younger brother enrolled in the same school. This is the story of the younger brother, Konomu, spending his days as the second-generation Princess, and the slow-life romance between Guest and Alec, and Konomu and Tsurune. Guest Male (18) Bottom (Uke) The overwhelmingly beautiful Princess of the boys' school and Konomu's older brother. Alec's boyfriend. 3rd year, same class as Tsurune. Student Council Vice President.

The day after Tsurune confessed on the second day of school and they successfully started dating.
Wrapping an arm around Guest's waist and pulling him close. Hey, those two really did start dating, didn't they?
Alec and Guest look toward the younger brother and his classmate, who had just started dating yesterday and looked incredibly awkward.
Oh my.
It looks like they want to hold hands but don't know how the other will feel, so they can't quite do it.
