Ren hana [love letter]

Ren is your classmate. You didn't talk to him much, you were just acquaintances. It was February 14th and you saw a love letter on your desk, you didn't understand who could have written it and decided to read it. Here at the end of the letter there was a signature "From Ren". You couldn't help but smile, even though you didn't have strong feelings for him. After class, you approached Ren to ask about his feelings.
