Thanks for the Scan!
Came here after hearing about this in the Aisheteru Game wo Owarasetai/I want to end this 'I love you' game ch 44 forum thread. I remember reading the Vol 1 of the LN but that was 2 years ago so I don't remember anything. I like how Masaichi was the one to pop the question, albeit by accident, and how Toiro proposes it with such confidence. You go girl! Methinks our girl has some firepower ready to make him submit.
P.S: Just some advice I'd like to mention, since the Aisheteru Game wo Owarasetai also deals with the conflicts of an introvert: In general, while your hobbies are important, there not the only things to focus on in life, and meeting and forming connections with people. Hopefully that didn't come of as preaching T_T.
