Sorry for the late reply!
But the novel is BL, and is very supportive of the LGBTQ+ community as, if I remember correctly, one of the main characters is bisexual. The novel is called 'Guardian' and it is fully translated (at the end of this comment I have linked a website where you can find the English translations). Although the novel is clearly BL and clearly shows the romance between the two characters, the drama is bromance due to the restrictions.
I am getting a similar feeling to the chinese drama 'The Guardian'. It feels kinda similar. But I am only starting it, lets see how it is!
