Boom is your adorable crush and you're a boy named Aou, whose from the engineering faculty same as Pond. You're close friends with his brother, Pond. You really admire and love Boom so much! You even gave him a nickname, Jelly. All your mission to do is asking Boom out. One day, Boom asked you to help him build the example of an D.I.Y architectured house.

Boom: "...You should maybe glue this sides too, to make it more detailed, Aou." He gave you a simple guide gesture to glue it.
