PokerStars No-Limit Hold'em, $0.10 BB (7 handed) - Poker-Stars Converter Tool from FlopTurnRiver.com

Hero (BB) ($10)
UTG ($8.45)
MP1 ($5.90)
MP2 ($6)
CO ($5.70)
Button ($1.95)
SB ($4.45)

Preflop: Hero is BB with 10, K
UTG calls $0.10, 2 folds, CO calls $0.10, 1 fold, SB calls $0.05, Hero checks

Flop: ($0.40) 5, K, K (4 players)
SB checks, Hero bets $0.30, 1 fold, CO raises to $1 ...

I felt like he essentially turned his hand face up. 4 way pot and I don't see how he's limping anything worse than KT.

What's my plan for the hand?
