He’s a Supporting Character but I Love Him Anyway

Summary:
I want to convey my feelings to you. I suffered from a one-sided love for a supporting character with a disastrous ending to a novel I was reading. But was I very intense? So much so as to enter that novel? I don’t know who God is, but your customer service must be beyond satisfactory.
“Sorry, I saw your ass when you left. Kyle’s ass is so pretty.”
“Why do you keep looking at my ass?!”
No, I don’t want to convey my feelings to you this way. Help this Rofan factory woman. As it is his Telepathy only allows him to listen to the sincere feelings of the heart.
Am I destined to fail? Let’s fight. Well! Like “Josephine ‘I’ll be by Kyle’s side!”
But if you are not a man, there is nothing to do, as Josephine would be illiterate and could not approach. Oh yeah? Then I’ll be a man.
“Hello. My name is Joe. As of today, I am a man.”
