Shalini shouts at Sachein, but Sachein informs Shalini, that he is so outspoken and does not want to write in the college wall to convey his love, which makes Shalini realize her mistake.
But to her surprise, Sachein informs that, although he has not written it, but the content present on the wall is true which means that he is in love with Shalini.
