Just finished the manga!

I just finished the manga and omg I don’t even know how to feel or act. I am so happyyyyy and I wasn’t EXPECTING THAT ENDING! After the major confession, I said I wanted them to be together but I didn’t know it would happen! I want a spin off like how did Tai-chan come to terms with his feelings….IM SO HAPPYYYY, I am moved to tears :’) Any recommendations for romance manga just like this would also be appreciated :))
