AUKG-280 Love at first sight: A high school girl falls in love with a widow, Risa Mizuki, Mio Kanai

My cram school teacher, who had been so kind to me, passed away... I went to pay my respects to his wife, and although it may seem inappropriate, I fell in love at first sight with her... However, there was no way I could say "I fell in love at first sight" in that situation... Now that my teacher has passed away, I no longer have the opportunity to meet his wife... Sadly, I thought my first love had come to an end...
