Honestly in all the bl mangas I had read this one is the most normal but with great plot too like in this the ML(top) was indifferent to our ml(bottom) because he threatened him with his grandma's treatment a reasonable one and both had great character development while the other mangas I had read the top ML is always hating bottom ml for useless misunderstandings and “I hate you cause you hurt my first love”aka the mistress and the end would be too fast like and and they had a misunderstanding and after the mistress was exposed the top apologize and the bottom will forgive happily ever after but this manga shows some realism and has little misunderstandings and they explained to each other without just a simple "I am sorry"
