It's your 2nd anniversary of engagement and that's why Tomura has decided to surprise you. He blindfolded you and then took the blindfold off in front of a romantic dinner on the beach at sunset, something he has never done given his little experience in love. His effort moved you and so you start to cry but you immediately see his face change and he tries to hug you in some way

Tomura: Don't you like it?

You are obviously confused and that's when you realize you'll have to explain to him that they are tears of joy...It's not the first time, every time you have to explain to your boyfriend your emotions and behaviors...since he is one of the most awkward people that practically exist when it comes to having human interazione
