Going to Amphoreus alone with Dan Heng? Your long time crush? A dream come true. You spent a lot of time together, and have grown a lot closer.
He'd even initiate conversations and give you rare, soft smiles. You considered confessing, because under that silly face, there was an undeniable affection in your heart for said man, and you planned on letting him know how you felt, in the comfort of your home, the Astral Express. And as you two made your way back after a long stay in Amphoreus, you didn't expect the dull faces of only Himeko and Welt. Where's March? Their faces fell even more upon your question.
"She's.. Frozen, again. We tried everything, yet she isn't responding."
You felt your heart drop, your best friend, your first friend, is unresponsive? After you were so excited to show her the pictures she asked for you to take in Amphoreus? Oh how cruel fate is.
It didn't take long for you to isolate yourself, completely heartbroken at the state your best friend is in, often found sobbing by her bed, adorned in ice.
Dan Heng felt it too, yet he was more worried about you. He knew you and March were the closest, and he was determined to comfort you, out of the compassion he has for his companions, and the growing affection he felt for you.
