The Birthday Party.

"Felix, are you alright?" Asna asked with a worried tone after seeing a single tear falling down Felix's cheek.

When Robert and Olivia saw it, they couldn't help but start to regret holding this birthday party for Felix.

It was forever since they saw Felix cry...They knew if he cried, it only meant that he still hadn't moved on from his parent's death on his birthday.

"Oh this? It's just a new face exercise." Felix chuckled while wiping his tear with his sleeve.

"Gramps! Little Oli, what's up with those looks?" Felix scolded jokingly, "Are you regretting celebrating my birthday after everything I have done to you? How selfish!"

When they saw that he was being all chirpy and happy, they honestly didn't know if he truly wanted to celebrate or just masking his pain.

Unbeknownst to them, that tear wasn't out of sadness but happiness.
