I first started reading this during my 2nd year of high school and now I'm about to graduate engineering but still Ritsu has not yet confessed properly. Kill me now.
If it helps, right now i checked it out, and there is a synopsis for the volume 15 on the wiki page. ALL SPOILER ALERTS INCLUDED. Check it out if you want. I am in pain right now. https://sekaiichi.fandom.com/wiki/Sekai-ichi_Hatsukoi_Volume_15
