Based on the monitoring of the Dusty S-cluster Object (DSO/G2) during itsclosest approach to the Galactic Center supermassive black hole in 2014 and2015 with ESO VLT/SINFONI, we further explore the model of a young, accretingstar to explain observed spectral and morphological features. The stellarscenario is supported by our findings, i.e. ionized-hydrogen emission from theDSO that remains spatially compact before and after the peribothron passage.The detection of DSO/G2 object as a compact single-peak emission-line source isnot consistent with the original hypothesis of a core-less cloud that isnecessarily tidally stretched, hence producing a double-peak emission lineprofile around the pericentre passage. This strengthens the evidence that theDSO/G2 source is a dust-enshrouded young star that appears to be in anaccretion phase. The infall of material from the circumstellar disc onto thestellar surface can contribute significantly to the emission of Br$\gamma$ lineas well as the observed large line width of the order of 10 angstrom.
