So basically takao held himself back from confessing hoping his feeling will go away after three years but apparently it doesn't so shin-chan takes the matter into his hand. Science says that whatever makes you fall in love just last for three years. Takao is an idiot but so does shin-chan tho lol. And whats the chance that shin-chan finally push the chance right when takao ready to crumble down tho? But yeah gusari's story always tug at your heartstring
Going under the belief that the sensation of being in love only last 3 years, Takao tries to hide his feelings for Midoriya so they won't ruin their friendship and be together forever. But, he just fall harder. Wow! This is totally relatable for me. The most you put effort in not feel love for someone the harder you fail. The funny thing is that you think all the way that that feeling is totally one-sided but, generally it's completely requited.
