I thought it was a little strange when Felix was eliminated and Hyunjin talked about Felix being like a child who needed all the love & protection. Not really in a patronizing way...? More of a fierce defender who will protect Felix against anything that might hurt Felix's sweetness.
Other members call Felix "innocent" sometimes, but it's not quite the right word. He has an open & sensitive heart, & so much love, & everyone wants to keep that intact.
