What is the পিয়ানো melody played in স্বতস্ফূর্ত S02E06 when Kurt & Blaine passed the hall hand-in-hand?

স্বতস্ফূর্ত S02E06, the latest episode. What's the পিয়ানো melody played in the background when Kurt and Blaine passed through the hall hand-in-hand.
The same moledy was played again when Dave punched Kurt at the locker.
Thank you.
