He hasn't even said i like you
Senpai doesn't tell his own siblings, dad, or matsuda that he loves them lol. I don't think he's the type to say that as straightforward as you may hope. But he does explain his love for Morinaga quite a decent amount in this manga
I know he did not just ask this man to marry him when dude still hasn't even said the words "I love you" after (our) 20 years of this manga...
