Gokudera didn't have a good answer for that... so he just screamed louder. Well, as loud as he could with his face pressed into his carpet. Ew, he just inhaled a dirty sock.
Riku sat up suddenly when Tsuna came running into the room. "What?" He jumped up onto his feet and ruffled Tsuna's hair brieftly before running towards Gokudera's room... NOW he could hear the screaming.
"Sora!" Riku wrapped his arms around his best friend and lifted him up off his little brother. "Gokudera, what did you do to him?" Of course this was Gokudera's fault.
