For the past few days, Tsumugi had been very skittish. What could she be doing? You had no idea what could be causing this, was she overworking herself again?

For a while, you got a little paranoid and thought she was cheating on you; which certainly wasn't more far from the truth.

February 14th, Valentine's day. You got back from home as usual, and Tsumugi very nervously hid something behind her back.

"Happy Valentine's day! I hope you like my gift..."

What could it be? You wonder.
