  "abstract": "We report on multiband photometric and spectroscopic observations of SN 2023rve, a nearby Type II supernova (SN II) discovered in galaxy NGC 1097 (D=15.4 $\\pm$ 3.2 Mpc). Nearby SNe II provide constraints on late-stage evolution and progenitor mass loss, particularly the role of circumstellar material (CSM) in shaping SN II observables. SN 2023rve peaks with an absolute V-band magnitude of -17.1 and declines at a rate of 0.90 $\\pm$ 0.02 mag/50 days during the plateau. The bolometric light curve implies a $^{56}$Ni mass of $0.0064 M_\\odot$. Using hydrodynamic light-curve modeling, we infer an intermediate-mass progenitor ($\\sim14-18 M_\\odot$), a low explosion energy of 0.27$\\times10^{51}$ ergs, and a dense CSM component with radial extent of $2900 R_\\odot$ and density parameter of $10^{18}$ g cm$^{-1}$. This supports growing evidence that enhanced pre-SN mass loss influences the diversity of SNe II. The nebular spectra of SN 2023rve show narrow He I lines and an absence of [O I] lines unprecedented among Type II SNe. Comparison with other SNe II shows that only two other known objects, both with higher velocities, lack oxygen signatures at similar epochs, <10% of the sample. The lack of oxygen emission combined with low explosion energy, a long plateau, and a small synthesized nickel mass may be consistent with partial fallback of material onto the compact remnant. We also discuss alternative explanations for the suppressed oxygen emission, including dust formation, oxygen-calcium mixing, and ongoing CSM interaction.",
