I have a feeling something will happen during the last few episodes. Something like drama, or a death, because things are way too happy right now, and knowing Madhouse and the anime they made, something has to happen that's sad.
Also, the title's name is, "My Love Story!!", so Gouda is probably telling us a story of his high school life and the girl he love, Yamato. So, in the future, Yamato could possibly die of one, an accident, or two, a disease. Idk, anything could happen.
I have not read the manga or any of the sources the anime is currently adapting from, but based on what I see so far, that's my theory for the future of this series.
