Love Comedy Manga ni Haitteshimatta node, Oshi no Make Heroine wo Zenryoku de Shiawase ni Suru

In the world of a popular rom-com manga, my only mission as the friend of the MC is to make the losing heroine, Sei-chan, happy!

"I'll definitely make you happy. Please go out with me."
"W-Wait, what!? Y-You're being serious...?!"

The manga adaptation of the sweet rom-com from Kakuyomu starts now!
